Re: Double hump heads
I am under the assumption that the chambers and runners are all the same in the pro-torker line. The vortec is really only referring to the bolt patterns. They claim to outflow the vortecs and all stock cast iron heads. I would also assume that the 2.02 valved heads will out flow the 1.94's.
Why would they build another type of head ? That wouldn't be very smart marketing. I wouldn't be surprised if the only real difference between the Pro-Torker's and the Pro-Action heads are the runner sizes. (same chambers)
