Get your stock heads ported by a good porter. There are several that frequent this site. Discuss with them valve sizes and decking the heads for a compression bump. Which leads me to the cam. There are much better choices available depending on your riding style and you should also consider going gear drive while you are in there. If you can find a good independent engine shop in your area, a better alternative is to have them bore and hone your cylinders. It's less expensive and yours are already seasoned. The other potential problem I see is the V&H BSS pipes. People get emotional about this but the truth is, these don't have a great reputation for saving the power inherent in the build. There are better choices if you do your research.

Almost forgot, I prefer the SERT but you need to find a tuner that really knows how to tune with it properly.
