I can live with that assumption. So by your interpretation I can adjust my oil pressure to 78 PSI @ 3000 rpm like my FSM says I can--right? Mine is right on the money so yes, I think I am Legal. I never said anything about different pumps being legal--just pressure.

A GCR is inlcuded with our licenses now...

See: 17.1.4.D.p

"All engine components not otherwise listed in these rules shall meet factory specifications for stock parts..."

There isn't much room for interpretation here. The parts must be stock, AND anything ajustable (not mentioned elsewhere in the ITCS) must meet factory specs.
