Maybe this has been discussed before, but it's news to me.

SUPERSONIC exhaust ports! Burn the mixture by the exhaust valve not all across the chamber! "Variable" port geometry using fluid dynamics!

Makes my brain hurt. Where do I buy 'em?

i prefer "road head" personally. :D

Good reading!!

I wish Mr. Fueling was still alive to be able to discuss this more fully..

I have read about the flat intake valve thing somewhere?? I am not too ure it wasn't in regards to an old British designed racing head at sometime??

But it also seems like it was in reference to the old Willis head that had the intake valve in the head and the exhaust valve in the block like was in my '52 Willis Areo Eagle??

This would put the combustion chamber over just the exhaust valve and not over the piston to help it push better upon combustion like the old flathead Ford motors were.

I wish more of this technical stuff would surface in our car mag's b/c it sure helps us to understand more of what is going on, cutting-edge tech-wise, imho..

All the "soft heads" where I work don't perform very well. :D
