But that swap just moves the issue to #2/4 ports so I cant see how it fixes the problem . Visard said the swap helps minimize harmonic vibrations but he has seen no real proof of that .
I agree! But tell the Chevy boys that chit. They think the 5&7 swap unlocks another 100HP. And that ain't no joke. ....but then, most of them think addin chrome valve covers add 20HP too, so........
