Ok, so explain to me what a "cam flow spec" is. All the cam does is affect how long the valve is open and how far it opens. It has nothing to do with how the air flows.

Port-matching, as I understand it, is matching the ports of a head up to the ports on an intake.

Joseph nailed it. We're not flaming you bro, just making sure you don't get scammed is all.

If anyone was really being flamed at all, it was the guy who was trying to tell you all that stuff about porting heads to match a cam.

If there truly was a way to match a set of heads to a cam by porting, people like Jay Allen, Ed Curtis, and Buddy Rawls would be out of business!

Normally, the routine is: Pick the heads that will support flow for your power, then choose a camshaft that will allow the heads to work in favor of your RPM, type of racing, powerband, poweradder, etc... Getting a cam and then making the heads flow to the "cam-specified" lift, duration, etc.. would work, but it would be a bit drawn-out.

And an F303 is beyond what a D8 or an E7 is capable of doing anyway... A B303 is about the most I would use since the lift is conservative but the duration allows the heads to breathe more in each given cycle.

aluminum heads are in the plans anyway but the porting is free and simple so i might as well to my e7s while their off the motor. thanks!

Taylor, just make sure you wear a dust-mask and have a fan blowing across the part to blow the iron dust and chips away from you. And Safety Glasses!
