Where the tip rides on the valve is not as important as getting the side forces minimized..........IMHO.

I was told this very same thing.
How does one check for 90 at mid lift without having a degree wheel or dial indicator?
This step is never expounded upon.
Also,there can be a 0.050 difference between PR lengths and available PR checkers. For instance,you measure a 9.25 on a comp cam checker,order the 9.25 PR through a vendor,and there PR could actually measure 9.20.
Will this generally cause a problem?
