CHECK ROCKER MOVEMENT ON BOTH SIDES.

Kind of surprised the lunati tech guy didn't say to check for rocker to retainer clearance first. Just a few thou smaller base circle on the new cam could cause contact that the old cam didn't have. That contact makes for some strange valve click/whack noises. Most of all...Contact is worse when the valve is closed because of the rocker body shape. That contact will also wedge out against the valve keeping it from seating good.

We're talking noise and backfire here

I took videos of both sides just posted the one side.

I will check for clearance between the rocker and retainer. Makes sense. Thanks.

This tech guy has a LOT of experience. I got the good one that is old and has GTO's. Pontiac guy. He heard my description of what happened and he went right to the cam and lifters being bad. Like he was sure. Maybe they have had a few bad ones? Or he was God sent to get me out the ditch on Good Friday.
Either way, he was very convincing. Knows the parts exactly. Knew all about the heads and springs.
