For 100 bucks buy them. Then you can still ride while you are waiting on finances to work the newer heads. For 100 bucks that a no lose deal. I bought a pair of t6-6 cams and a pair of worked heads. The heads were done by dan Vance. I can't wait to bolt this together. I am hoping for 100hp/100 torque bit will be happy with whatever I get.
I am not racing the bike but I sure like the idea of just twist of the wrist in 6th and fly
