Cylinder Head Porting and Power Production

Have you ever wondered why? And yet guys like Dan Smith makes so much power with ported OEM heads that everyone throws away to buy after market heads?

If cylinder head flow is everything then why does Dan's engine make what it makes with less? Does anyone ever ask why? Is his engine just a fluke of nature or the exception to the rule. Why does he only run 28 degrees total timing?

Why Why Why.......

Umm are you aware of the very reason I started this thread? J.Rob
