I have two of the 4 into 2 type, air injector fittings removed and holes tapped

very deep for socket head NPT plugs (so they fit nearly flush with the port wall).

Header flange holes are drilled out so you can use 5/16" stainless bolts.


You would need to order socket head NPT plugs from Victor Machinery in

NYC (cheap by the hundred) or probably could get some from an engine

builder (they're used as oil gallery plugs on race engines).


What I have left are #3 and #4. $52 shipped.
