SM Head Install... forgetting anything?

DentalDart said
Well drivers side is on. Used some of my old 5/16×18 7/8in header bolts for the 2 shitty bolt holes and the new 5/16x18 1in bolts in the other holes with a washer. They are all snug on their. Ill get the rest installed tomorrow... to bad I dont know how to keep the a/c off the car, which would incrase hp (by not taking it due to having it on) and lighten the overall weight of the car by the billion pounds it weighs...

I haven’t had to deal with this issue for years but I still remember what a pain in a butt those couple bolts were. You may have me looking at the set of Speedmaster heads I’m doing for my sons 340. I’m going to see if there’s enough room to plug those holes with aluminum bolts, grind the heads off, and redrill new bolt holes that are moved out.
