Thanks guys,
my buddy's dad has a race engine shop and is going to hook us up. Took the heads over on Sunday, the valves are ok and the heads are flat. He doubts it needs a valve job but will let me know if they do. we need to machine about 0.030" off each intake spring pocket for more coil bind clearance.

So i am good for now.

TTT got the heads back together. Found one intake valve bent and it was replaced but now i have one intake leaking water when the intake runner in the head is filled with water.

Any advise? I am going to call the guys mentioned above to see what they say.

The machine shop i took them to, told me that all of the valve "suck up" or draw vacuum.

I found the intake valve leaking after i tore the heads down to add shims and i did not bother to leak test the valves first.

Yar, I would send them out again and get a valve job done. After that I would make sure the machine shop decks them anyways because I will put all the money in my bank that those heads are out more than .005 from middle to end because that's the way it is. You should really find a reputable shop to do stuff like this (unless you can do it on your own) because stupid shit like that doesn't get done. Now you're out another week at least until another place actually fixes what's wrong like it should have been done in the first place.

Never mind, i found the problem....me.

I measured install height on everything with one set of hardware, assuming they were all the same. turns out they are not. not sure if the variability is in the retainer or the valve locks yet as i am still trying to figure it out. so, my bad and i am sorry.
