[QUOTE="96blak54, post: 1363473, member: 14727"] I get what your saying. The down fall here....only so much flow can pass through an orfice/valve hole. Flow through any exhaust valve is debatable, but intake valve has its limits just because of hole size. Max porting can make or break power potential within an intake port. The 4.6l head can be ported just like the 5.4l with no problems. [/QUOTE]
