Check out the corral, www.corral.net, technical articles, powerplant, then the ported gt40 heads vs ported stock (Mustang E7TE)heads. Shows flow numbers for untouched GT40 and mildly ported GT40. Port work and article done by my good friend Pete Turek 5 years ago. Basically, 185/130 cfm I/E at .500 lift.

I used the information in those comparisons extensively when I had my GT40s ported. Good stuff. They have the Twisted Wedges on there as well now, I think.

Ok, just dug up a very nice site with flow charts of common ford heads:

http://www.fordmuscle.com/archives/2...ds/index.shtml

TFS twisted wedge flow substantially more than 185 intake at .500. More like 240 according to the tests these guys did. Compared to 210 for the GT40X.

Definately a URL worth bookmarking.
