okay so i have a 6 port 13b... the previous owner had a 4 port racing beat intake on it with a ~400 cfm carb. im told that will choke out a 6 port engine quite a bit. wondering if i can port the 4 port manifold out to work alright on a 6 port engine. or if i just saw screw it and get a new one.

thanks guys
