I'd stay away from HV pumps. Too much load on cam sensor drive gear and the kits often end up with less pressure than a good stock blueprinted pump.
Buy a quality stock length pump gear set, drill the idler gear for oiling, deburr the gears and glass bead them, radius the sharp 90 degree turns in the cover with a lond round carbide burr. Set end clearance to .001-.002 using plastigage and a gasket kit available from TA performance. A steel wearplate is also a good idea.
If your bearing clearances are correct, you'll have 35-40 psi at a hot idle using 10W-30
