"Because at some point...it really starts to mess up valve train geometry."
Too bad nobody's figured out how to address that...
With a little work in terms of valve job, valves, and springs/hardware, from what I saw, these heads should be able to reach the level of a stage 2 ported RPM for $500-700 less. There's a ton of potential there and it's too bad you are being negative about them. Saying otherwise makes Hughes look.. well.. stupid for lack of a better term. I had a good look at them in Carlisle on Thursday with Sam.
