Default I've done many searches and haven't quite found my answer...

I've been searching for a week or so now to try and figure out what head gaskets seal the best under boost when using a 4 bolt style head. I've seen people have success with both mls and copper. I'm trying to see what gaskets have held in the most power with a forced induction combo. I know most of it is in the tune, but the gaskets still play a roll. What is the consensus? I ran GM12569365 with my last setup on spay and had no issues, but wasn't sure how well they would take the boost setup.

Default

use copper after you o-ring the block and or head. cometic mls gaskets love forced induction though. It depends on your cylinder pressure though. Most important part regardless of what gasket you go with is the deck and head make sure their perfect.
