If you have the head ported and polished by a competent flowtech you should see increases of 10 to 15+ percent in exhaust. Exhaust is the bottleneck.

The head is where all the power is built. I always suggest to my customers not to skimp on the head. In a FI situation where air/fuel is being forced in to the motor, everywhere the air/fuel travels should be modified for maximum flow. Oversized valves get more A/F in and out of the motor. Porting allows more CFM's to flow and polishing increases the velocity of A/F passing through and over the metal parts.
We also do a little trick with the way the A/F enters, combusts and flows past the valves to increase the throttle response by 40%. (Area 51 stuff, can't go into detail)
