Well guys you can only install the lifters one way. The roller has to be on the cam lobe. If you try to flip it over your gonna have big problems. And the flat sides need to run toward the front end for the lifter trays to fit back over the new lifters.

They only fit one way in the trays and it doesnt matter what side the hole is on. I used the "LS7" lifters and they had the holes on the sides if i remember correctly......

the holes on a hydraulic lifter dont matter which way they are installed, they just take in oil from the galleys and pump up the lifter...thanks everybody.
