I have a pair of new bare Blue Thunder heads for sale. They have Yates style ports and 50 cc chambers. They appear to have a lot of improvements over the older A3, B3, C302 and C302b heads, but still use Cleveland rockers unlike Yates heads. They also require a lot less port work then C302b heads.
The cheapest I've seen them is about $1700 at:

I'm asking $1500. I prefer to sell them to someone in or near Orange County so they can see exactly what they're getting, and I can arrange to show them to a serious buyer.
