Before I go and bother PMO for a dozen plugs I figured I would see if anyone had some either left over from a conversion, or from a set of heads. These are the 12 x 1.5 plugs used to plug up the MFI injector ports if you are converting to carbs or EFI
Here's a picture of one that I have. I need at least 8 and would take a dozen so I have a few spares.
