ok... im sure this has been asked over and over.. but i can not find any examples or advice ANYWHERE. anyhow, im looking to mill a set of heads i have off of a 2004 v6.. they are going on my 2001 v6... i want to be able to run pump gas and i am wondering if anyone has any suggestions on how many thousandths i should mill them.. i have access to a chassis dyno and i currently use canned tunes. all of my internals are stock.. it has a 3.39" stroke and a stock compression ratio of 9.36:1.. id like to reach 9.75:1 or maybe, MAYBE 10:1 if i could.. can anyone help? all advice is welcome.
