Guys, don't worry, nobody is offending me. I've got a pretty great sense of humor.

In the interest of keeping this thread informative, Ron Iskenderian recommends that "the spherical radius on the cam face should be between 60 and 80 inches for best results" when running his Isky 88 regrind.

Furthermore, it dawns on me that as the difference between the "96" radius" and "flat"is only 0.0013", it's not at all surprising that a great number of NEW Ford tappets are FLAT, because NO OTHER SPEC in my flathead manual is held that tight. Am I wrong!?
