What oil pump you getting?
For reference, if it's even a comparison, my brother's 181K-mile LM7 averaged 20s-30s at hot idle, +/-40s when cruising. With a Melling M295HV swapped to the blue (lower pressure) spring, it stays at 40-45 cruising and hot idles at mid-30s. At 5,000-6,000 RPM, it'll hit ~70s. This is with cheap 10w-30 dino oil. When I first put it back together, I ran 15w-40 Diesel oil in it as part of the internal cleaning. The needle went past 80 at redline. I'm glad I swapped in that blue sprig before closing it all up! I was ready to do the @kbuskill resistor mod if it was gonna have too much pressure.

gm 12612289, says standard volumn/pressure but sposed to be the right one for my truck which should be HV? not to concerned with having 80psi just would like to improve it

Who knows?! Melling supplies GM for their oil pumps (or at least they did) and I know the AFM engines got HV pumps. I don't know what OEM number crosses with what Melling number or anything about your 6.2 with VVT. For an engine being raced, I like higher pressures for the upper-RPMs for more "cushioning", so I either shim the stock relief spring or swap out the spring depending on the motor (new, old, etc.). High pressure at any other time is just wasting power. Your original pump should've been fine, so there's gotta be something else for the lower pressures. It shouldn't have all that much wear at that mileage, either. Maybe the VVT engines normally run lower pressures? Just thinking out loud.

The Melling M365 is the 12612289, High Volume Pump with Yellow Spring.
