The objective with studs is to be able to run higher torque #'s than conventional head bolts for more clamping power. Studs are to be run in to the block finger tight only - and their suggested torque #'s are with their lube. Fastest 300

Good to know ( and check ), although the paper work I got with my ARP studs did not discriminate between iron and aluminum heads. If you can't clamp with higher numbers than with regular head bolts, studs are kind of a waste - unless you take the heads off and on - often. Fastest 300

BB or SB Big block ,,,,,, Probably doesn't apply, but FWIW for a small block, stock head bolt torque is 90 lbs. Edelbrock aluminum heads recommend 95 lbs. I run eddys in a blower application with equivalent CR of 16.1 ( and more )at times. I run mine up to 105 ( believe that is an ARP recommendation ) with MLS gaskets. Fastest 300
