With performance bearing clearance on the rods and mains - around .0025" vs OE at about .0015 - and/or full groove main bearings your oil pressure would be typical. I'd bump up to 15W40 diesel engine oil and call it good. 15 psi shouldn't hurt the engine but I'd be happier with 20 at hot idle.

With OE bearings/clearances, I'd call that a bit low. Suggest you get the info from your shop as mentioned above on bearing setup.
