The choice is yours, depends what you will do for pistons. You want to keep compression around 9.5 to one so target a head and piston that do that. 9.5 should work well with the blower.

Chamber choice will depend on the CR you wanna run, I'd keep it lower and pick the piston and chamber to make it happen for the boost you wanna run..
