Thinking of buying a set of imco powerflows setup for big block chevy. They look like the correct "A" riser setup for mercruiser but appear to be just missing the bung on the front side of the riser. Can I have a bung welded in or would I have to get another set of risers? This is going on my injected 454 magnum. Here is a pic of the powerflows and an arrow to the bung I am talking about. Shit now that I think about it not sure if I have the fitting for those on my manifolds, damn now I gotta get home and look lol.

Call imco but they wanted like $300 to weld in an O2 sensor on mine
It should be doable since I welded
O2 sensors in both of mine
I found a local welder that could do it
For less than $100

Awesome thanks. Now that I really think about it I think the top part of my manifolds have a plug in them with no water line I just can't remember right now so those imco's might be correct for my application. For some reason I was thinking they had a bung with a water line coming out the front. Think they are setup like this diagram.
