Ronzara:
If you choose ARP ask about the the set of bolts and/or studs that have a reduced shank diameter for the short fasteners. The reduced shank stretches and helps retain the clamping force on the head gasket. ARP has done research that has shown the studs without the reduced shank diameter will not stretch enough due to their length and will relax, losing the clamping force and allowing a head gasket to fail in certain circumstances. This is not commonly known or understood. Fel Pro offers high quality products too. The current trend and requirement in gaskets is to create a seal and still allow the movement required by the different expansion rates of aluminum and cast iron when used together.
