Head Gasket went south yesterday.... Now that I'm doing the head gaskets what can I upgrade? I don't need anything over the top but a few gains in HP wouldn't hurt.. Any suggestions? I will only be paying for part cost no labor.. I have a real good friend who is a mechanic and has his own shop. I dismantle and he puts everything back together. Do I need to change to ARP studs? Reason? Any and all comments welcomed... Thanks
