new 360 oil pressure problems

well guys i checked over absolutely everythin nd i did what i didnt want to, i tore into the motor took the intake off nd valve covers and tried priming it and found my problem...my racer brown roller lifters are goin up in the bore too far and letting way too much oil to go out...so now my options are new cam setup bush the cam galley or try differnt liffters. nd im planning on doin the easiest, try different lifters where the bore goes closer to the roller (like a stock magnum roller lifter, the racer browns where solid rollers)
