Default Which head gasket?

What would be the best head gasket to use on a 94 lt1 that is putting roughly 350-400rwtq down with stock heads?

Part number too, if you have it?

Cometic .027" 4.01" bore to get your compression up.

Look at the Impala head gaskets. They are .029 thickness. I have used them on every build I have done with great results.

If you use Cometics, Make sure your surfaces are freshly milled as they are designed to be used on speced surfaces.

If this is a garage replacement use Felpro - they are great and are able to fix the minor spaces in an unmilled surface.
