I installed a 1999 Thunderstorm engine in my 1994 Sportster and was wondering if R&B Racing LSR 2 into 1 headers work well with the N4 (SE497) stock cams? I have installed a HSR42 Mikuni carb and a 27 tooth front pulley on it. The headers worked well with the previous engine and I was wondering if it would hinder the SE cams?
