    472 part number question

    I've got a '74 472. There is a tube from the air injection pump that runs between the heads. I want to remove this tube and block the ports in the heads. So I need some plugs. Does anyone have a part number? Will Napa have something?

    you might be able to find those at NAPA. If you can't get them there, check with your local speed shop. If they don't have them they should be able to get them. That same plug should also be on the opposite end of the head if you need one for reference.
