With an OEM gear, yes. It shoudn't be too deep into the metal though. Basically just the black phosphate coating gets worn off.

​​​​​​ there isn't a Groove, it's just the coating wore off. Thanks for the input just wanted to double-check.

is there a problem reusing the plate? The motor only had 32,000 miles on it when I tore it apart. And you are correct it is assembly Lube.

A new one is only $18 why reuse it? that seal can only be compressed once really. its what seals off the front lifter gallies from leaking. Plus it wears on both front and back.

As I recall there is an inspection procedure in the manual for re-using the cam plate that includes inspection of the gasket on the back of the plate. If you go with a new plate, I would get one that is the same as the original and not use the newer tapered bolt design from GM that replaced it.
