As regards your sig: the bible appears to deal in plenty of lies itself. ;-)

#22 has an enclosed oil crossover passageway. This is important on a 3.4L 603.97x or on a highly boosted/tuned 3.0L. On a street car, any #17 or above head is a "definitive" fix for the 3.0L cracked head issues. If you're running a 3.0L and just have to have the latest head, they're worth the money. Otherwise, a #17 or higher is perfectly adequate.
