Roller cam idle RPM

Oil pressure in park cold is 80.Once it warms up it stays around 65 to 70 in park but goes back up to 8o with rpm.In gear warm(around 900)it drops to about 45 but once again climbs back up with rpm.

I just realized something this morning that I didn't notice last night(it was late). You have a roller cam so it's hard for me to see anything could happen to that cam with the oil pressure you have. Even if you drop the RPM down some more. Now I'm not a engine builder guru or anything. Send a private message to BJRracing, or moper (with a "e") and see what they say. They build race motors.
