I have an 09 Road Glide with 5000 miles on it and just purchased a 103 stage II kit and am wondering if I should get a set of 103 heads to compliment the kit. I already have a heavy breather, Rinehart slip-ons and a S/E race tuner. Do you need to run diffferent cams and pistons if you switch to the S/E heads? Would I be better off sending my stock heads to someone for some porting and polishing work? I really want more performance but dont want to sacrifice reliability. Contemplated a Procharger but its just too much $$$ for now. This is my first time to your site and would really appreciate your thoughts.
