Did you use a shaft to drive the oil pump without the distributor housing on it? If you did, the oil didn't get to the right lifter galley because the distributor housing wasn't there to complete the galley passage. Try priming it with a primer that includes the distributor housing.
Ditto, Pump the engine up, turn the crank 1/2 rotation pump it up again repeat until the the crank has been turned 2 rotations. If still no oil, start taking things apart and find out why.
