Best head gasket for high boost application?
Best head gasket for high boost application? As the title says, whats everyone using? Ive used the Ls9 gaskets but havent had much luck with them but most wasnt due to the gasket but tuning. Still curious to what everyone is using. Thanks
Ls9 is going to be the general winner here. I just received my first set yesterday, will be going on the GTO shortly 
I've used other GM MLS 3 layer gaskets for years up to about 1000hp and 20psi with decent results too.

How much power do you want to make? Boost is not really relevant. I like the MLS gaskets to 1000-1300hp, after that I like either copper with o-rings or the fire rings from Andreas with a graphite gasket.

previously made a little over 1000 with the ls9 gaskets but either due to the tune or the stock heads kept lifting them. Now going with a different set-up and wanted to know, plan on power being around 1300-1400.
