Hi Sal , There are two holes , one in the front and one in the back , plus they put restrictors in to resrict the amount of
oil going to the rockers . Let me know if you want me to stop by , I would pull a valve cover off ,show you the dove set up I got from George A. Guessford .
Sal let me know if you still may want that bell housing / plate .
I was on you dyno with the green car , John Martin
