440 Oiling mods

I ended up turning the cam bearing and blocking the passage there. Then I did the mod from Big Block Dart, drilling the holes through the valley into the oil galleys. I then tapped the deck surface and bought plugs available from the hardware store. I have needle roller rockers and havent fired it yet. Im starting with a .045 hole in the plugs. The bad part is having to pull the heads to "tune" the oil supply, but oh well. Im in the middle of a move and will probably be a couple months before I fire it up.
