If a Powervalve cover that is a little bit bigger than stock is better, then how about a Powervalve cover that is a LOT bigger? Is there a point of dimishing returns?
For instance, what about adding a 1/2" spacer behind the cover?
Or what would happen if the valve was "open to the atmosphere" (I mean, what effect would it have on the powerband, beside the problem of introducing foreign material/dust!)
