High Oil Pressure

Do I need to worry about seals?
It's not in the car yet. Should I continue with it and see what it is once the engine is broken in? Would hate to pull it again.

It's a '76 block .030 over with:
KB pistons
509 Comp Cam
MP M1 Dual Plane Intake
Edelbrock RPM heads
340 HP Exhaust
770 Holley Street Avenger
