The old PN was 8950-16 and had two large oiling holes on either side. Oiling was too much and didnt work well.

Here is Comps new solid roller lifter PN 8956-16. I have no idea how much and they dont seem to be in a catalog yet. But I belive if you call Comp direct you can purchase them. they are alot like the old ones but there is only 1 smaller oil hole per lifter and its oriented towards the center of the motor (rear of lifter). Should work fine. they are very very light and short body. And I prefer a link bar as well.

 

One positive thing about the link bar....the lifter CANNOT drop into the holes with the cam out...lol. just an FYI.
