Ive been thinking about ordering a Jay allen cam. But they need flow numbers to order one. I thought about having the heads ported then flowed but i just wonderd if anybody knew how much a set of pretty much box stock older Twisted wedge heads flowed? I also have a ported cobra lower intake, its matched to a 1250 gasket and has alot of work done to the lower. Anybody ever flowed a ported cobra intake?
