Gary Lewis Posted December 4, 2019 Share Posted December 4, 2019 Is the early head sought after? Better than the smog heads? Link to comment Share on other sites More sharing options...
1986F150Six Posted December 4, 2019 Author Share Posted December 4, 2019 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
