hi
we had the same problem after a head repair .ended up the valve lifter followers are graded and the ones the engineering shop used aren't .
replaced them with good used genuine mini ones of the same grade and all sorted.
we found the problem by manually winding the cam lftmotor from one extreme to the other and measuring the valve lift .
hope that helps
