Is the early head sought after?  Better than the smog heads?

Not really. I just thought it was neat as it seems to be left over stock of something old and was remanufactured to Ford's standards.

That actually appears to be the 240 head. Looking at the combustion chambers they have a kidney bean shape rather than the "D" shaped chamber. If that is the head that gets shipped out then I believe that would be the sought after early 240 head.

Which would raise the compression by ~ 1/2 point!
