Porting 010

Compare this view down the exhaust port to a stock head. More effort goes in to the exh port, because it is relatively worse off. My goal was to get the port to 75% of the intake flow, with a bare port(no helper pipe), using average flow numbers taken at valve lifts of .100", .200"... etc up to .600".
