For the non believers on the B1-BS heads:

First the heads have been worked big time by EPD (Larry Olson). A max Wedge port (kind of) with a 2.250" intake and a 1.800" exhaust, 60cc chamber.

Injected on Alky, tunnel ram, 2-2 1/8" Injectorators.

Final compression is 15.3:1

When I find the dyno sheet I will scan it and post it. I was just trying to get the fuel curve close so I didn't push every last drop out of the motor on the dyno. I know one pull it made 867hp @ 6500rpm, the motor is supposed to go 7500rpm easy and there was no drop on the HP curve @ 6500.
