EFI Bung in head update

Bill. my new idea is to CNC mill 5 mm teeth into the back rim of the pulley/balancer itself. I realized my fan is about an inch from my balancer as is so I cant mount the pulley in the front and the front lip already has a huge scallop out of it for some reason, maybe balance? anyway, got some stuff done today. EFI head on block, intake and plumbing all mocked up. waiting for new head and intake gasket. Found out my really old EFI head has NO alternator bracket bolt hole! Oh man, back to the drawing board....
