I think the port work will really wake up that motor.
I second the idea that higher stall speed, maybe 5600 rpm would go with that combo.
More stall might be a good idea but the stall speed will increase naturally from the extra torque so I'd try it first. The car will have more power so the MPH will go up so I'm not sure it will need more gear. The trap RPM will probably increase from 6700 to 7000 just with the additional power and speed. Might not want anymore RPM than that depending on what parts are in the engine.
