Lowering the head also retards cam timing by as much (not a lot)... I'm not against modding, actually. None of my engines are ever left stock. I did remove sharp edges and smoothed out from the exhaust ports' outlets, smooth matched the intake flanges, advanced ignition timing, replaced exhaust, removed subthrottle plates and exhaust PAIR valve... A thorough porting job with the valves removed from the head wile the head is off would yield better gains. The squish band needs to be measured to determine optimum head shaving rate, and possible remachining of the combustion chamber.
