@furrystump no one had head studs when I ordered these. As for gaskets, it's a felpro blue gasket 1008, compressed height is .53. This is the same part number gasket we put on the car 2 years ago. It worked the past 2 years, so KISS
Are those heads closed chamber? Do you know if your pistons are out of the hole at all? I am putting Edelbrock closed chamber on my 340 and trying to figure head gasket thickness, etc.
