I was taking a set of patriot gold springs out of a set of heads,and was going to reinstall them in the L92 heads,but one of the keepers was broke. Should I replace all the keepers or just the one that broke? Are the keepers wear items?

 

They are cheap, so I would replace ALL of them if it where my motor.

 

I agree, I wouldnt reuse the springs either.

A broken lock is probably a hint that the valvetrain was out of control and has taken a beating already!

 

Yep, another quality patriot product. But instability is an issue somewhere in the rpm band causing issues.
