Here is an overlay with some changes.. I played with header diameter and length and this is the best I came up with. Leaving your cam selection and head selection alone still at 11-1 cr..

Changed the program from a 1 5/8 24" long header to a 1 3/4 30" long header
Changed from a 750 carb to a 1050 carb
Switched from a 1.5 rocker to a 1.7
