I have a 3k 600 and need to know what size headers will fit on there....750...1000??? I dont wanna lose any back pressure...I guess I just need to know if 750 headers will bolt right up.

Normally but not saying now of days the 750 was swapable with 1100 parts with the 600 being a model of its own. The 750 had same casing and such of the 1100. Now then I'd figure a 600 isn't going to fit. But try to find out size like talk to reputable used parts guys on ebay and such. I still don't think a 600 is going to take the big brother 750 and 1000 header sections to the heads. But you never know.
