Cam Bullet Racing "GeorgesP" spec, hydraulic roller tappets tuned with very little play, almost like solids.

Are you SURE that the valves are closing COMPLETELY? Incorrect valve adjustments are one of the things I would be looking at.

I always prefered solids where I could measure the clearances with a feeler gauge rather then ATTEMPTING to pre-load hydraulic lifters correctly. I always had difficulty with "high performance" hydraulic lifters. They are always a "bear" for me to get right.
