Hey guys! Well this month is gona be big for me getting new kibble valves and complete spring kit(affordable for me)and wanted to ask what port & polish is out there, since I'm going to gut out the head I think I'd be dumb not to port it. I've heard of a drag port, mx port, and mild port, but don't know the difference and gains they have. I have a 453 je 13.1 bbk like chinoduca has, old style hotcams, fcr 39, DID cam chain, stock stroke hotrods, full sparks, and velocity intake. My riding is weekend warrior, like to hit the track, do some trails, and want to hold my own on dune drags. I would apreciate your guys info on this or any other suggestions about other ports that I didn't mention. I don't want to go stroker though, thanks in advance!
