Also part of the spec was "checking clearance" The duration was measured after the lift at the valve hit the opening checking clearance then finished when the lift was at the closing checking clearance . It was good to have" big" checking clearances sent in by the factory . Overlap was checked the same way . NHRA tech had a really trick Degree Wheel that simplified the checking process .
