I flushed the motor twice, changed the intake gasket and still there is not enough oil pressure to the top of the motor, I took the oil pressure sending unit off and pressure checked and the bottom of the motor is 90 psi, what could this be?

Is there lifter noise? What is the reason you think oil P low? The oil get's there via lifter through push rod and onto rocker. Is no oil getting to rockers?

Yes ther is lifter noise from all the lifters, the psi from the lower part of the motor is 90 psi, also the rods seem to be fine, all the noise is from the lifters and it seem like the oil is barely seeping from the lifters and I never seen all lifters rattling at once.

It maybe loosing preassure at the camshaft bearings. If really worn oil will drop back in block instead of oil galley for lifters. One or two lifters noisy because of gunked up I could see but not all and both oil gallies pluged not likely.
