Comp valve keepers- Is this an issue??

What do the old locks look like with the new retainers? Not sure what you've got for a cam but on milder stuff I just use the stock retainers and locks on the 901-16s. My truck has the std retainers on the factory "rotator" exh valves with retainers from an old 318 I had lying around. Maybe just use the stock retainers and locks for the intake side and forget about it?

The old locks fit fine in the new retainers. The valve on top in the first picture below is with the new retainer and old stock lock. That's likely the way we'll go.

He ended up getting new retainers because we didn't like how loose the stock ones were on the 901 springs. I know some people say they've run that combo before, but we didn't want to cut corners. They old retainers are .070" smaller on the OD and .060" smaller on the surface than runs in the ID of the spring. That seemed like an aweful lot of slop.

So in general valve stems whether intake or exhaust "dont care" what degree the locks are?

Exactly. As long as the locks match the retainer.
