Low power and crappy mileage came about due to the drop in compression that just so happened to come along with the open chamber, but it does not have to be that way!

And you have something way the heck wrong, as closed chamber heads require more timing then open chamber heads to make max power, its just that the open chamber heads can be more prone to ping and knock if compression ratios your looking at are are kept equal.

Anyway have we gone off the rails in regards to the OPs original question here, sorry about that!
