There isn't really enough meat in the block to gain much plus there are better ways to beef it up.

For a milder build, say 500-550 HP, a set of main studs plus align hone with stock caps works well. Next up would be ductile iron or billet steel main caps with studs. Next is aluminum main caps which seem to absorb harmonics that cause cap walk. Then there are girdels. All with 2 studs.

I went with the steel caps on a 550'ish HP build to have some room for upgrades later (head and cam).

Good luck!
