tapping..

ok so as some of you know my motor has a little 'tapping' coming from the top end. Happens when its cold, then quiets for a little bit then when the motor is at operating temperature it comes back and its noticeable at all rpms.

lifters and cam have all of 1k on them. oil is full and still clear. its coming from the drivers side cyl 3/5. there is no power loss or anything, ive adjusted them several times and using stock rockers. this problem was there with the old cam/lifters so they were replaced but its still there.

Im thinking the moron who cleaned the block didnt do a good job and a oil passage is restricted or something. if no one has any ideas im just gonna wait and beat it up til it blows and get a 350 and be done with it. haha
