Are you sure the cam was not damaged when the lifters were changed, The one photo of the cam seems like the lobe is wearing bad.

When you adjusted them, did you make sure the the plunger was not down a little then you went another 1/2 turn? I go 1/4 turn after 0 lash, but you have to watch the lifter close to make sure the plunger is not going down bwfore you tighten it.

Cam lobe
Watched real close to see when plunger just cam off clip and then 1/2 turn.
This is with 7/16 studs with crimps nuts, fine thread. The original lifters had a few that ticked a hair to much and one was spongy. The new lifters have been very quiet after a few seconds once started. just was looking to see if wear was normal, considering I swapped lifters Last year. I thought if wear mark went clear across nose of cam, lobe was considered worn. Gerry

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
