new lazy lifter....
Two sets of Comp lifters and still taps when started. 80 lbs pressure cold. Comp said they had a bad run from a vender. I had and old purple shaft cam kit here. Installed the lifters and its fine. Most lifters from venders come from the same manufacture. Pontiac take the same lifter as mopar. they have the same issue now.
Have them send another set and keep swapping them. until you get a good one. You can swap them without pulling the intake. they can be removed on the driver side rear or passenger side front they fit out at that spot on iron heads. Use a good magnet and a screw driver to move them back or front. No gaskets required. Aluminum heads must use the dist. hole. Its a process but can be done. We just did it. on this Demon.
