Oil pressure-How much is too much?

Are you running a 180 or 195 thermostat? Are those readings basaed on a hot motor?

Is the engine broke in completely?

If so:

Redline 5w30 synthetic. Plenty of zinc ( I realize you have rollers). Or run 10w30 conventional Rotella T. Napa has store brand 5w30 syn on sale quite frequently.

No need to spend horse power pushing thick oil past the relief valve and also thru passage ways.

Thinner oil returns to pan quicker for more available oil at high rpm, flows better thru oil passages, arrives at upper engine more quickly during start up.
