OK so I am considering different (Aluminum) cyl head options for my TT engine. Goal is to make around 800 HP on pump gas with around 9 PSI. CID will be somewhere between 415 and 427, dart lil M block, standard deck height, 23 degree. I am looking for a relatively "good out of the box" cylinder head which I won't have to add too much assembly work/cost into, I would like to just do my port matching and be done.

This is my first foray into a turbo application and I'm reading everything I can on the subject. It is of course easy to get into the stratoshere with head options (Do I really wan't/need sodium filled exhaust valves??)

From what I'm reading for this engine I'd want runner size to be in the 220CC range. static CR around 8.5:1.
