Man i'm in a tight spot trying to track down a head. I got a V117 missing the front head. Model number is 90-1050 F but when I got one off of ebay the stud pattern was too narrow. The rear head I have fits and its a 90-1050R. S&S is telling me those were specially made for the Big Dog Evo style motor 4 1/8 bore. Anybody know anyone with one of these Super Sidewinder style heads?. Appreciate the help.
