timing tools used? was the head ok all the valve springs ok etc?

Possibly a belt tension issue: When you did the belt change you should have put the tensioner to its mark and then spun the pulley run (by hand) 4 to 8 times and then re-checked/adjusted the tensioner accordingly before locking up tbe sprockets and removing the lock tools... did you do this (be honest)?
