I used Wood TW-6g's with mild headwork. SE breather and White Bros. E-pipes. The heads were shaved for a 9.8:1 compression and had a 5 angle valve job with minor exhaust and valve clean-up. The work was done at Baltimore HD. The bike runs like a top with very little cam noise and absolutely no pinging. I just had her tuned at Frederick HD in Maryland and was delighted with the results. Honestly the numbers were not my main concern. I was going for a great rideable scoot with excellent low end torque for my '05 Road Glide. I couldn't be happier! What do ya think?
