Sorry Roger--------But if his heads are set up for only .520 lift because of springs he needs to start there with mods to allow more cam to make up for some lack luster basics-------He also only has a 650 carb----he'll need bigger cfm------headers are probably 1 5/8 and maybe 1 7/8 would be better and shorter tubes to help higher rpm range


about only thing leading him away from street set up was 5 - 600 gears


he posted twice, hasn't been back??????
