As you may know my LS1 has a little bearing issue. I have already purchased an Lq4 that someone has built for themselves that has the ARP stuff down low. I have stage 2 LS1 heads, Fast 92/90, LTs full bolt ons....minus the EWP.

Trying to find out how to get the best bang for compression. with a .610 lift cam. Should I just drop to a .020 gasket or have the heads milled? I will be spraying a 150 shot at the least. This is an M6 Camaro. I am trying to make up for the extra 88 lbs.

 

I probably wouldn't run that tight of a gasket. If you are looking for more compression, I would run .030-.040" gasket and mill the heads the rest of the way. Make sure you have proper PTV with whatever cam you are running. Let us know if you have any other questions!
