I remember reading long ago that stock caps/bolts were totally fine to 550+ hp, and later that if you push to the point that 4 bolt caps are needed, a factory block itself becomes the weak link. I do not have any knowledge whatsoever to disagree, but I DO have a set of billet caps on hand (donated by a good friend), and the block IS going out for machining, so, I guess that unless it would actually hurt the bottom end, I'll have them installed as thanks to an old friend.

Any opinions on studs vs bolts? Wondering if heads or mains should or shouldn't.
