Yah but how much money did they have into their Eddy's and who did it. I can assure you that the guy who did mine was nowhere near their skill level....I'm not 100 percent sure but I'd think that guys running 9s with eddy heads have probally gone as far as to have the pushrods relocated and using offset rockers.
I looked at what Hughes big mouth CNC costs, to get yah in or near the 300cfm mark and it gets pretty damn expensive..especially after shipping the heads from canada, to them and being shipped back. Not to mention the costs of using their rocker set up.
