Fuel Pressure Adjustments

I have a 95' non-turbo Eclipse (420a). I put Stage 4 Crane Cams in and up the compression from 9.6:1 to 10.5:1 + other mods. ( underdrive crankpulley, adj. cam gears, knife edged & lightened crankshaft, lightened flywheel, ported+polished intake man. , Ferrea valves, springs, +retainers, Iridium spark plugs, 8.5mm wires, 4-1 headers+cat-back exhaust, venom injectors, and an AEM adj. fuel regulator)
How much fuel pressure will work for this setup without damaging anything? And if there is anything I have overlooked in building this motor please don't hasitate to suggest it. Thanx.

the bottom end. rods and pistons especially.
