So I went down to the boat today and visually inspected/verified that the new oil pump does not have the adjustment screw in the relief valve. Definitely keeping it that way. I haven't found anything regarding higher pressure during break in but I'm still researching that in the Buick and Pontiac forums I have some experience with.
I'll keep you all posted...

IMO, it's always best to run and test a rebuild on the floor before being installed. It would have been easier to deal with a possible rebuild issue that way before going through all the trouble of installing then possibly removing again to remedy. Once you're happy that all is running well on the floor, and reading are normal, then install.
