Nice, what size thread are those allen plugs?Today, replaced the manifold gasket(s). Had been running the Remflex gasket, did not work for me. Probably operator error. So I got a pair of Fel-Pro gaskets and a can of Copper Coat. I also had 6 of the metric plugs for the air rail holes, and while the manifolds were off, put those in too. Replacing the 1/4" NPT plugs I'd had in there.
