Justone: I took a look at the flow data from your earlier posting, and then created an Excel file with the data that allowed me to compare different heads. You are right: the GT-40 heads fall off and go flat in exhaust flow at 0.3" lift. So, I'm taking them off the list.

AFR, Trick Flow, and Blue Thunder all seem to rate pretty high, but I have my doubts about using these on a street/track Cobra, as opposed to a track only Cobra.

I'm looking for a good head for street driving and road racing (Laguna Seca is a mere 40 minute drive away).

Any thoughts?
