Re: Aluminum heads
I use bolts on all my heads . I use hardened washers on the aluminum heads. I torque all my heads to 45/50 lbs over 3 heat cycles. I like to use copper gaskets. Although it maybe wise to use a grade #8 bolt, at 45 ft/lbs , any bolt will do. With 24 bolts torqued to 45 fft/lbs that\s more than a 392 Chrysler hemi in clamping force.
