Is it for a truck or car? They are different as to where the exhaust exits. The car exhaust is centered under the carb and the truck is forward of center by about 3".
I do not have any but Red's Headers makes a dual exhaust header.
those pics look pretty good, i think your manifold is better than the one we have now. how much would you want for it? you would be sending it to the dayton ohio area. let me know, thanks mike
