Steve: The only thing you didn't mention was whether you actually checked
valve clearances to see if you had a mal-adjusted (loose) rocker.
Although it sounds like it is coming from the valves, check the Woodruff key
in the pully (harmonic balancer) on the crankshaft. Easy to check - (with
engine off ;-) ), move fan back and forth and see if the pully moves.
