what size head studs do yall recomend 12mm or 14mm?

 

most likely 12's the 14's reqiure the block to be drilled and tapped and the head reamed and are for all out competition. A set of 12mm studs a marine gasket and orings are probably all you would need even for twins/nos ect.

 

this is true

Regular studs can hold up to 80 psi, far as ive read.. At that boost level ur well over the 600 horse range..

bigger question, which are the ones taht you dont have to grind the valve covers with?
