Horse a piece, but if i were building it i would use studs, even though the blk will have blind holes and if you're useing a tricky rocker setup it's much easier to re-torque the heads with studs. IE, jessel shaft with 1.530 springs. $50.00 difference is not a lot on a good motor.
PS, Todd you have 5 bolts around the cylinders,VS 4 with a s/blk
