Yep, not much to do. Just gasket match it and go maybe 3 inches into each runner, check the size of the carb flange holes and open if necessary..maybe blend the lower angle of the flange/plenum. Whatever you can reach..if we are talking dual plane..hey maybe put a little notch, like 3/8-7/16" and about 1/2" deep...or a 3/8 thick 2 hole spacer and notch it instead. Get a 2'fer out of that..mid range tq and more rpm capability. That's where I'd start.
