Huh? On ALL 911 heads, the intake is on the top of the head, and the  exhaust 
is on the bottom. To minimize heat transfer, their solution was to bury  the 
exhaust port WAY up in the finned area, and made the port as short as  
possible.

Moving  the exhaust down and behind the intake might require heroic measures 
to get  enough cooling  action.
