While tearing the engine down I noticed that the guideplates have some wear from the pushrods. I'm running Pro Mag NSA with hardended pushrods and GM guideplates. Is some wear normal? A couple are pretty bad (one may be from when a rocker came loose).

I used a pushrod length checker when I installed everything and the rocker was in the correct place on the valve stem. The plates are flipped the correct way. Rolled the pushrods across glass, they don't seem bent. I even adjusted the guideplates as much as possible to center the pushrods in the grooves. On a few of the plates the wear is on the outer most edges of the intake and exhaust sides, so adjusting wouldn't help anyway.

Any thoughts?

Did the search already, was hoping for something else. Not really sure where to go from here other than to recheck the pushrod length after rebuild & assembly.

 

i'm not sure if its normal but i had some wear on my GM guideplates also. not all of them either, just 2 or so
