Well hell I didn't know that the offy manifolds had a water jacket full length. I thought there was just a hollow under the carb !!!
I might not have started this whole thread if I had known.
The offey intake was ment to be used with the stock exhaust manifold that area is for heat Not water. If you make new plugs for the bottom and weld them in OR epoxy over the plugs that are there Then You can ad water to that intake. Other wise they will leak water.
God doesn't like ugly.
