Personally I'd prefer the FT piston and 75, but there's another $500+ piston adder to the bill, for street use the dish would probably be ok.
Now the question is, will the 72 chamber already be in it and can I mill it down to 65, or have chamber profiles for smaller to larger, and made to order?

* CNC machined 72cc and 85cc heart shaped combustion chambers for on the shelf
heads
* Heads will be cast without combustion chambers so custom combustion chambers
can be ordered to customers spec's
