SB rockers hitting springs and retainers

You have geometry issues.

Call Mike at B3 racing engines and tell him what is going on. Switching rockers won't fix a geometry problem. May make it worse.


Google B3 and talk to Mike.

Easy fix really.

^X2 ^this is your answer , if you really want to understand rocker geometry go to his site and read his three part series on it then call and ask him your questions , I will be getting a kit from him as soon as I start my refresh , it's at the top of the parts list .
