indy "x" heads or edelbrock rpms?

Thanks for clearing that up crackedback, is right I'm looking at the new castings from Indy.

I will be getting ahold of Brian at IMM for an order.

I had a best of 12.86 in the 1/4 when it was a 4 speed. With these changes is it too much to expect low 12?
With the Indy heads and his lower priced port job, I would say low 12s should be a lot easier.
