The engine block was cleaned when it was disassembled. I'm running 5W30 oil because everythine's so new. Pump is new. ALL parts were purchased through NAPA. Is it possible these are the incorrect lifters for a 402? Maybe there are others that will fit but not be able to pump up or line up with the oil galleries. I'm just throwing out guesses. I really have no idea what may be causing this.
