    Default 401 buick nailhead engine torque spec

    i am pulling the heads off of the turbo nailhead for some blending and porting. i wanted to know if anyone had the cylinder head torque specs and head bolts torque order. also looking for torque specs for intake, water pump, timing cover,crossover, and the oil pan. I bought a eastwood powdercoating setup and it is better than sliced bread!! everything is getting powdercoated while it is apart. Thank you
