If you do not get enough clearance on the valve this means that the valve stem
is too long!
Valve stems must have a certain length which must be checked every time the
valves are ground in! Probably you did not check the length (or the former
owner?) when reassembling the cylinder head, or worse, the valve seat has
suffered from recession so the valve goes in deeper into the head. This must
then be rectified by taking some length off from the stem!
Have a nice season with your MMM-car.
