Ok the lifter issue has been my main point of discussion since joining the forum.
I documented my expereience in this thread, but upon further investingation I have some major quandries...
I'll grab a pic of the entire cam shortly, but here you can see major pitting and material wear on multiple cam lobes, with one major one.
When I replaced the lifters, one was stuck (corresponding with the worst cam lobe). I later found out the center pin had walked out slightly and was hitting the side of the lifter bore.

This lifter came out of cylinder 5 (drivers side, 2nd from rear) which is a non MDS cylinder.... part number
