What would it matter what side?
I think that is normal MK cam wear Tim.
Heads and Cam have to be tuned up every season. Try some 800 grit.
This is a Marine Kinetics cam after 35 hours, see normal.

Dammit Joe beat me to it.

I'd confirm 100 % seat and open pressures all good and no coil bind. Then probably making a phone call or going for a drive with cams in hand.

My crower cams or your crane 8620 billets didn't look like those, and they've been around the block quite a few times.

Obviously you want to cover all avenues. However this not being the first or an abnormal ordeal kinda lends to what the issue is.

Mine have a little mark. Can you feel anything with your finger Tim or are you too busy kicking the dog and throwing tools??
