Problem with the BA head is it's not much better than an Edelbrock when compared to each other in ported form.
The engine in my post used Indy heads, and had we started with the 210 runner or the -1 heads and filled them I think we would have made alot more avg. power.
I would have liked to use a 4.25 crank and keep the bore around 4.125 or so. But that's the way it goes....
