I've run 25psi on numerous applications with 4-bolt heads and that is on the 'regular' ARP head studs.. Now we use the L19 studs in these applications.. .Have numerous 8-9 second cars in this psi range all day long. The nice part about a 4-bolt block also is if you send a rod through it, you just didnt punk a $5k block
Unreal: Buy Camper's Novi 2200 kit, you know you want to.. :P
