Seller is advertising these are RAII heads from his 68 GTO.

He includes images from his photobucket account of a 1971 Firebird he dismantled. The #96 heads have a 1970 date code on them and are D-port heads. I hate it when people intentionally mislead on parts. I just hope some poor sucker does not purchase them thinking that they are RAII heads.

Shame, really.
