Finally started up my new hemi build and am a bit concerned with low oil pressure!! The pressure is around 18psi at 900rpm idle and only goes to about 25psi at 3000rpm. These are my specs:

Indy 426-1 Legend Heads with no oil restrictors
Indy roller rockers with Indy shafts
Megablock Hemi bored to 4.375
Eagle stroker crank stroked to 4.5
Eagle Rods 7.1
Diamond pistons with 10.5 to 1 compression
Solid roller cam
Solid roller lifters 829-1
Smith brothers pushrods
Milodon deep sump oil pan
Milodon high volume oil pump with internal sump

Should I put the oil restrictors in the heads?
Is there a bigger issue hiding its ugly head?
Any suggestions would be greatly appreciated
