340/420 90psi Oil Pressure During Prime

Good point on the cold oil and I have cam lube and pre lube grease all thru this engine.

I forgot to mention that the 90psi was on both 1 and 2 with my drill. I kept switching back and forth between the two gears as both of my batteries were losing their charge.

I am going to try to get the heads primed tonight but I might use my older electric drill for a more consistent speed.
Thanks again!
