I know George had talked about seeing these from I believe the SEMA show. Well I was looking through Summits site this morning and saw them for sale. They have two differant items for these heads, with a $1900 price assembled and $2100 assembled, I read through the descriptions and I could not find the reason for the price differance but here is a link to them.
TFS 351 Aluminum Heads

PS I just saw the difference is the spring set ups.
