I'm going to guess its a GT-40P but I could be wrong They more than likely came off of an explorer. I'm not sure if the Cobras had just GT-40 heads, P heads, or something different.

*edit* took off my picture since Seth edited his post and added pictures to it

I don't think any Cobra's ever came with the P's just the Explorers. There aren't any emissions hook ups on the back of the heads are there?

So are they good $....? money and can I put in my Stang

I would go for it, if you have any doubts about them, run 'em down to your local machine shop and have them checked out for any leaks, cracks, or warpage.

Gt-40p heads came on Explorers and can make for a quick combo. They are cheap too.
