Leave the 130's, they're perfect for a turbo setup. Changing out rockers is cake, takes all of an hour maybe a little more. There's writeup's on CLUBdramai'mabunchofjerkoffs on how to do a cam, you can just take the rocker portion since that's all you need. You just need stock pushrods, no need for "new" ones. I know for a fact there has to be a handful of people on here that have pushrods laying around, especially james (turbo400i'maddictedtowhiskey). Just keep asking questions, you'll be able to make your own writeup for your specific situation vs what you'd find somewhere else.
trying to decide on what to do for turbo build

Yeah, if you want to upgrade to comp pushrods for the piece of mind that's ok, but the stock ones are perfecto. Turbo's are awesome, you don't even need a cam. You can run a stock cam, stock rockers, and a nice 90# spring and probably go 11's. I'm going to give it a shot with my DD since it's completely stock. Things only on 9psi and it's faster than my other car when it was Gen V, cam, headers, etc. 
Im pretty sure the old z7 kit has a T3 flange so the stattama T67 wont bolt on with out a swapping to a T4. A T04e 60-1 would be a nice bolt on upgrade from that one and still be able to make as much power as your trans will allow. And there under $800.
I vote for the stock rocker/s1x/130lb spring combo as well.

Yeah, I thought about this...but wouldn't I get away with buying a new crossover and DP for the T67 and then just swapping it right in? thanks for the help.
I am definitely going to pull those 1.8rr off there after hearing everyones input. I have a stock L67 sitting in my garage from the GTP I just tore down. I can pull the rockers and heads off of that and just swap them over to my block. Maybe someone would want some ported heads or 1.8rr somehwere? Now that my car isn't burried in the snow...time to move that bitch into the garage and get to work!
let me know when you start to pull the monte. also as 10sec. said, rockers are cake. i can get them done with you in about 30 min. quit acting like a stranger and give me a call when you work on shit. you have my tools, and ill bring my beer so i dont have to drink your skunky ass shit. and i need to bring you them spares and what ever else you might need/want.
i also need some of my extensions back...i had them all in my tool box when you took it and now i dont have any, makes working on shit a PITA.

Haha, no prob man. I have a day or two off after tonight. We should meet up so I can steal that spare and get this GTP to the scrap yard. You can get whatever you want from your box. I have a couple extensions from my own set I can use.
I will hit you up for sure. I just tore the GTP down in the middle of the night when I had a couple of days off..the Monte will need closer attention to detail and some help for sure.

Yeah you could swap crossovers, Dp, and turbo, But what would be the point in buying the z7 kit to start off with?
Id keep the ported heads on unless you don't have arp headstuds already installed.
I disagree, lose the ported heads. They're worth good $ that can be in your pocket or put towards something in the build that will make power. The heads will offer no benefits to you until you're in a power level you'll probably never get to. A person such as yourself can do the head swap no problem. FWIW, phatride has gone 11.1@124mph on 19psi and stock heads. There's much more room for improvement on that. Others made well over 500whp on stock heads. Kalo's Impala made over 600whp on stock heads.
I'm not arguing that stock heads wont make all the power he will ever need. But guessing he has studs in his current setup, it would reduce down time to get the build up and running. If money is a big factor and you can decent money for your heads, then go for it. As mentioned before, you might as well swap cams if your going to tear it down that far.
Might be a smart idea to have your springs tested too if your going to swap them.

Thanks, I thought I could do that. I got the z7 kit used. Plus I am not swapping the turbo now anyways...unless I win the lottery. I will only go t67 when I change cams and maybe blocks. I do already have the arp head studs in...should make things a breeze but I have never messed with the head studs so who knows.
You guys make some good points and have good info here.
A). Kalos impy is fuckin nasty...I would only hope to get my car that fast.
B). I have thought about it and it is either use my current set up just to see what she does, or I can sell the heads and use that $ to get a st5 cam, and put a chunk down on a new set of plogs or some other mod.
C). If I did put used heads on I should prolly replace the valves retainers and all the odds and ends, so that will cost money.
D). I could say fuck it, run it till it breaks and then build it up the right way.
Either way, if I can't get a buyer for the heads they are prolly going to stay on. I am not in a huge rush to complete this build so I could take my time and take the head off, change cams, and mess around with some other stuff. Although...The quicker I get it together, the quicker I can race.

It really wont matter, even with 350whp you wont be putting power to the ground on the street
Not to mention that cars race weight was easily under 3k iirc
IN for traction bars
Yea, 10.008 i think was it's fastest time (something really close to that) and they stopped. I would have kept going until i got a 9.999 or faster but
Yea it was like 10flat, ALMOST lol... i think they stopped cause kalo figured he could be in the 8s with another RWD platform for the money he dumped into that imp
Yeah, those traction bars were crucial. I wasn't even able to keep my old set up from burning the tires until I was past 50. 40is when I would go wot and yeah still chirped the tires until I got traction. After driving the turbo gtp I just tore down, traction is a myth. Tires might help a little, but not enough.
I wonder if a company would be willing to custom make a end all 1inch plus chain for us. Strong enough for stupid amounts of power.
I am just looking forward to getting the car running strong. Even wth my old stuff, I never got it dialed in by any means.
PLUS, if this car breaks right away on me again I am going to think about a long term project maybe rwd conversion, or some type of tube chassis for rwd. I realize buying a lsx would be easier...but the only ones I like are vettes and for that money I could have a bad ass rear end and a block to get me started. I have been tossing around this rwd conversion b/c I would finally be able to get a bullet proof trans and have all the power I want.

Btw, I doubt I will be able to find a buyer for the heads...but why is it that ported heads don't matter on a turbo build? Let's say same turbo car with same mods goes up against its twin, but the 2nd car had ported heads. Would the ported head car not make more power...oer spool turbo quicker or something?
I really have no idea that is why I ask. Thanks again for the help

Turbo's make up for restrictions by running more boost, more complicated than that but in a nutshell, that's it. The power you'll be able to make on a current trans (even with a 1" chain) is limited to ~500whp if you want to make more than a couple passes on it. There's just no way to run the pressure needed to keep the clutches together when you're making 500-600whp. We don't have a transmission for that. That much power put through even a built trans will eat up clutches very, very quickly. You'll be replacing a trans every season.
Ported heads aren't needed until you REALLY get into the power, but everything else has to match it. You won't be able to run plogs, you'll have to build custom headers, you'll have to build an intake that will flow what the heads will, you'll have to run a very large turbo to flow what the heads flow... you picking up what i'm putting down? Nobody will get to that point, and if they do, GL finding a trans to hold it. Car would have to weigh less than 2500lbs to make it down the track more than 1-2 times.
Turbo's are just different, it's much too complicated to explain in detail, but they don't need cams, big lifts, ported heads, etc. A lot of people run stock cams, because it's enough. In our case the cams really do pick up quite a bit of power though. Nobody has tried yet, but a BONE stock 3800 with some valve springs (the stock ones would float) can go 11's, all day, probably deep into the 11's. I will prove this at some point this year. The thing is, everyone tosses in a cam if they're putting on a double roller, or they toss on 1.9 rockers when they do springs. A 90# spring on a stock cam/rocker will be enough for 18-20lbs of boost. This would easily get 11's and much more. Nobody has been able to run that much boost without some big time valve float. At that point, they toss on more than just springs, and it's really not needed at all. But hey someones gotta do it.
So, confused yet?
