I have 2 sets of NOS GM lifters that I decided to take a sample from and examine more closely. The attached pics illustrate what I found on several lifters from each set. Not sure what the black area is on the outside of the lifter body in pic A. Thought it might just be something that would wipe off, but it does not. The top rim of the lifter in pic B seems to be crudely finished. It seems to have various nicks, scrapes , etc. Not sure what the pic C of the foot of the lifter tells me.

I don’t deal with these things often enough to know what to expect them to look like. I thought every surface of the entire lifter would be surgically pristine and perfect, but maybe that is unrealistic.

Do you guys see any problems here?
