3800 Rockers

[TonzKnock-G]

What brand of rockers would you recommend?

Do I have to have a DHP PCM in order to take full advantage of rockers?

Thanks for all opinions

ABOUT how long to install? of course by someone who has done them before

I'd go with reworked stockers, there's no proof full rollers are better. If you went with full rollers, the ZZP comp cams ones look like winners. No offense to anyone with the HS rockers Intense carries, but too much money for pretty rockers you'll never see.

OH, almost forgot. I like to say a first timer can do it in 3-4 hours, and if you've done it before about 2. It's hard to say...some cars are more trouble than others. The actual changing takes very little time, but you need to remove quite a bit to get the VC's off.

Im guessing reworked rockers means modified stock rokers . Who would be able to do something like for me? How about the PCM? can it still be stock? thanks Ron your always there for a quick answer.

 

[imported_Ron Vogel]

PCM can be stock...I was 13.40's with a stock PCM still. You'll get more out of them with raised shift points; say about 400-500rpm higher. Rockers don't feel like much until the upper rpm's, then they come alive.

do valve springs also... better safe than sorry. at least 95lbs

How hard is it to do springs, I am really Wanting rockers but am kind of afraid to tackle springs.

Valvesprings are tricky unless you know how to do them properly and have the proper tools. You will need an air compressor and air hose (to pressurize the cylinders to hold the valves up, and also a spring compressor tool. It is not something that I recommend trying unless you are confident in your abilities, simply because there are a few things that can go wrong and sometimes it is extremely frustrating.

 

[syP]

ask ron vogel on that

 

[imported_Ron Vogel]

That's why I made my own valve spring tool.

 

[BumpinGTP]

I use the Snap-On tool, very easy to use and I can do valvesprings in 1/4 the time with this over a conventional compressor

and if you drop a spring retainer, then your night has a tendency to get really ugly

I don't know, anyone work on lawn mowers? or honda's?......., both should be about the same
All joking aside, once you have to rocker off, the spring has to be compressed, and there are two half-circle tapered retainers that when the spring is un-compressed hold on a little ridge on the valve spring, easiest way to get he retainers out is with a good magnet, otherwise they are kind of a pain, then the spring comes right off. If your not sure or not confident in doing it, it would be best to have someone next to you to show you a couple, then they are pretty easy.

thats basicly how the lawn mowers came off. Compress the spring and slide them off...can become very frusterating when you have to do it, yet alone the whole classes.....well i had to do everything for everyone in that class no wonder everyone i helped got A's

they make a small spring compressor tool, could be the snap-on one that bumpin was talking about, but that made it a piece of cake, getting those bastard retainers back in takes patience, I dropped one and it took me 2 hours to find it in my engine compartment at 3AM

 

[BumpinGTP]

This is the tool that I use, MUCH easier than conventional compressors. I believe Ron made a similar one. It is less than $25 directly through Snap-On.

Yup, that's it. Mine's not as pretty, but that's the best one to use.

 

[Blownbyyou]

I am thinking about buying rockers, 1.9 gen 1's, no matter what I should get springs, what ones I heard ls6 springs should work, any comments.

 

[BumpinGTP]

Go with the LS6 springs, they work well in that application.
