Offset locks to replace exhaust rotator retainers

Using a stock intake spring with an intake retainer on a 2 grove exhaust valve will actually change the seated pressure from 70 lbs to 120 lbs, allowing for a "used condition" seated height of 1.500 stock to a 1.600 installed height (the attempted combo from above) and the open pressure changes from 172 lbs to 212 lbs at a low lift of .400 inch . coil bind IS not much more of a pull on the spring tester.
