I assume that since you are running dome pistions that your E heads are not the 72 cc version?
With that Crower Cam and your CID you not going to need to shift above 6000 rpm, so I would shim the pump for 70 psi and call it good.
All 455 cranks are crossdrilled from the factory so they oil the Rods some 30% more then the 3.00" main journal cranks as it is even without the use of half groove Bearings.
The added pressure is needed strictly for the 4.210" mains.
Any unneeded pressure and rod side clearance will only serve to put more oil draped around the rotating crank & Rods and this leads to a power loss and potential oil control issues
