Found one of the first roadbumps on the engine buildup. I need to know the factory "Effective stud length" as well as the "base thread size" and the "base thread length". Seems the ones we used werent long enough, and the rockers dont want to stay in place. We are going to change the studs, but I need factory sizes to determine the new length to order. Then if I still have a problem, out come the poly locks.

Q

 

Anybody?
