Poll on are you running Stock or Modified engines

I do have a stock 340 square bore intake laying around but it is in rough shape..can cast iron be welded ? Some of the cast around the carb bolt holes is a bit rough,it would be nice to weld it up and grind it down if that's possible. I also have a Thermoquad intake somewhere also. I suppose I could make it "stock appearing" if I caught the bug to do so.
