I found this link on Lifter Rebuilding. He talks about "linishing" the top of the shim with P240 wet sand paper on a super flat surface. To me this would remove the "record pattern" the cam put on the top of the lifter shim.

" You will now need to linish the tops of each tappet, this can be done by using P240 wet/dry paper using WD40 as a lubricant, put the paper on a flat surface (a machined pieces of steel or a small sheet of glass) and then rub the base of the follower is a circular motion over the paper, make sure you turn the follower regularly as you linish, keep going until there are no scuff makers present."

i think i've got 1 or 2 head's worth of used lifters from a 928S3 engine.
some have dark circle wear marks, some look fresh.
you can have em all for $2 apiece + shipping. (have to count how many i have for a total).

Thanks for the offer, but I have 32 nice ones to choose from. Still trying to decide if my cam is good and if I can refurbish the lifer to re-wear with the cam. I am looking for it in the WSM to measure the cam lob. I am learning a lot. Thanks to all for the advise and expertise!

If my cam was bad, wouldn't the pitting be in the middle of the lifter shim? This motor hasn't been run for probably 3 years. The other 3 cam lifter shims look good with no pitting.
