Have your friend buy a set of Eddy RPM to start with and have them ported My 3450 lb Duster has gone 1030 with a set of RPM CNC ported by Jeff at Modern Cylinder Heads I switch heads to a set of M.W. port size Indy SR and the car has gone 9.96 at 134 MPH in the `/4 mile on Oregon 92 octane non ethanol pump gas, motor only through the full exhaust with the air cleaner on Jeffs work is great
