If I'm reading this right, I would have plugged the galley at the deck and redrilled though the plug. You don't have to block the oil galley to the head on a magnum conversion cause the head blocks it for you.
I didnt even think about that........good idea. But it is pretty bad, the gasket would not seal tough from what I saw if that was done. If some type of filler was used around the outside of the plug than it might have worked. If I used the LA version, I would have had to buy valve covers and NEW roller rockers cause I aint did got nun............so I saved a few bucks there.
