ive got a set of 706 heads ive had ported and what not. I was looking at getting them milled to bump the compression up a little. I have a 2000 tahoe was wondering how far i can go. Will be using stock gaskets... any help?

 

Well not sure if it helps but I got my heads milled .030" and supposed to be around 10-1. But if you mill them your going to want shorter pushrods to compensate for the heads being milled. Where in east texas you from?

 

im in henderson tx. I have read that i would need shorter push rods. I have 7.4's now with a 218/222 .567/.569 comp cam.

 

well you really cant say anything about the pushrods until you get the heads in there and get a pushrod length tool. Usually everyone has slightly different results
