Don't take things apart wild guessing at this.

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
