Randy,
If I were hoping for a new cylinder head it would be based on the four cylinder Fontana head(racing use). The ports appear to be huge.
Is a cut and weld hybrid feasible for this head similar to Leo's small block hybrid?

The Pontiac Iron Duke 4 cylinder heads can also be used. They share the exact same bore spacing and bolt hole locations, so you don't end up having to modify the deck surface of the block as you do if you use the SBC heads. They are pricy, and then you have to buy (2) of them to cut up. The Fontana heads are also pretty expensive. I think if he could come up with a newer casting that was kinda' the middle of the road between a siamese head with the bolt-in lumps and a ported Kirby head, that would be a good starting point. Something that started off flowing in the 270 CFM range maybe, and then had the potential to exceed 310-320 CFM for a fair amount of money would be a pretty successful new product, I think....
