Did you have them CC'd to arrive at that number? Most of the listings I see indicate that they are supposed to have 118/119 cc chambers, and I have a set that were actually CC'd by a machine shop at 124 cc's.

2ton, you might actually have better luck selling these on the chevelles.com or the camaros.net sites. These sites both cater to the hot rod crowd, have free classifieds, and you will have a lot more folks who are looking for heads like this for their projects. Not knocking OSO at all, but a lot of the guys on here are looking for the bigger square port heads. Good luck.
