Re: Replace head studs with bolts?

I believe the hex nut size of the originals is larger than the modern day replacements. I don't know whether this would be a problem, but wanted to point out the possible size difference. Also, the washers used are thicker than normally found ones used these days. The tapped engine block holes for the studs may not tolerate the torque of a bolt. The studs are just screwed in to a firm tightness, but the bolts will require about 65 ft. lbs. of torque. I have heard of going from bolts to studs, but not the other way around. Howard makes an important caution about the cut and rolled thread types.
