600-700rwhp no point in touching the motor. If you are pulling the heads then do it to upgrade the heads/cam, not just swap gaskets/studs.

I would do a head gasket and studs, I was at 620 wheel and my head gasket blew at the water jacket and put a hole in the #7 piston and scratched the hell out of the sleeve..

Or...if your tune, octane, or fuel supply is inadequate, you need all kinds of help. If the previous mentioned items are adequate, you don't need to worry at mid 600's.

If you have a crappy tune, crappy octane, or poor fuel supply....the greatest head gasket and studs won't help.
