Review on Competition Cams 630 16 Installed Diameter by Kenny Marozas

The motor I am building has a spring set at a low level and needs to reduce the number of shims you need to use. The spring height set is 1.900 and using these locks -0.050 might help but the problem is I see a 0.030 difference between locks in the 0.065 to 0.095 range when using the same valving position, valving and bracket but the Locks to be changed. I use a micrometer altimeter so accuracy/resolution is not an issue and the sensor is tested in a number of ways.
