OK, I have in mind a nice conversion for my winter project. But I'm still debating whether or not to have the NRHS stage 1 porting done to my 883 tops. I know I have read about the XB heads, but they are way out of my budget. I plan on having my jugs bored by NRHS, and Andrews V4 cams (86-90). How much is the stage 1 head porting worth throughout the powerband on a relatively tame conversion. Worth it??? Or should I just go with a head clean up and 3-angle valve job?
