Hey guys, need some quick help. I bought a set of mixed ratio comp cam 3/8 stud pro magnum roller rockers for my ZZ4 heads, and 5 of the poly locks that came with them are too tall and too big around, and won't quite seat against the rocker right. I'm not sure the guy can find the right ones, so I figure I better start trying to figure it out. Anybody know what part number is for the correct polylocks for these? I included pics. The smaller one is the correct one. Thanks in advance.

 

If you have,a pep boys near by they stock polylocks in the speed equip aisle. You can see them in person if you need them quick.

 

Nope, no pep boys within a half hour of here.
