Chopper Tony, http://www.leesspeedshop.com/ Get ahold of Lee at lee's speed Shop he all ready has them made up. I have done just what you are talking about but it's a lot of work, you need to make new guides and use sportster R valves, Lee has it all made up for you, so its just a matter of putting it togather like a standard guide replacement and valve job. go under what's new on his web site.
