Oil pump question on my future motor

I always order the M72 and a high pressure spring, also, but I've been told that the high pressure spring is now the standard spring in all their pumps. Not sure on this so I just throw one in. Don't forget to clean it all out and check clearances.

I used a high volume pump on my first Mopar rebuild in 2008. I ran it with valve covers that I cut the top out a bit. I was pretty shocked how the heads just flooded. I think standard vs high pressure is an argument that will always be heated. I personally have never needed the high volume pump.

Someday my bearing clearance may be on the bigger end of OK, and I just might change my mind....
