Forgot to mention... refining the cam specs included less seat duration to help with my low 10:1 compression. And I also upped the seat pressure by about 15 lbs with the cam swap, always wondered if that had much influance with better valve control
And a side note, not to 'knock' the Tomahawk intake in anyway. The test I did was done with obviously more cubic inches in mind and the "300 cfm" heads it was marketed for. It was port matched to my 2.300" tall port openings with some runner blending, no plenium work to speak of. Cliff Ruggles helped out and it compared very favorably with my Dave Bischop modified Holley Street Dominator intake, a very, very nice intake by itself.
