looking at the 2 intake ports in head and i'm looking at 2 bbl intake runners. i would say if i blew foam into runner and took it out the cross section would be smaller than pair of ports at the cylinder head. questions: does this speed up the air? if i keep the runner 'full size' up to the carb base plate will it be a 'dog'? do i want a smaller runner? have a nice day!
