Only one good piston choice in my opinion. Icon IC687. Careful planning and measuring 10.5:1 CR with the Stealths is possible.

Have someone like PRH massage the heads/valves. No need for full on CNC porting.

Modified DP4B or an RPM Performer. Which ever you want to work with with your hood.

Cam intake in the 230 degree range,

I really like my small venturi (1.375") 950. Drives like a 750, runs like an 850.
