ported head, foam pod filter and higher flow exhaust... Then the eventual jump with a 70mm piston 'big bore' kit increasing displacement volume. I haven't noticed much performance difference in elevation changes 0-1000ft. above 1000ft might be a different jetting situation. |

More air = more fuel. with my ported head and cam I run a 38 pilot jet and a 145 main in my PE28.
