Hmmm....this is interesting. I was unaware that there were two different gt-40 heads made (not talking about the P head either). I can't find real good info, but it seems like there was the GT40 that came on the Cobra and it had the 60cc combustion chamber like you said. The GT40 that came on the crate engines and the Lightning have 65.5 cc chambers. I think I will make a new post on this to see if anyone has any good info. Most of the articles that I can find just refer to the GT40, not taking into account if they are from a Cobra or Lightning.
