DDD, 250 to300 for the headers, on the head shave, you have to be careful on the head you pick, if its one of the open chamber heads like mine, you can shave a little bit and be fine, but if the compression gets above 9to1 it will hurt instead of help, the flame travel with the open head is enough better to give several more hp by its self. our motors are 6to 1 or about, the open chamber head will raise that to almost 8to1 with out the shave, add two carbs, two exausts, and it will make enough hp more to tell a BIG difference.
