Yes, it didn't leak diddly... I ran it with a carb on a homemade adapter on the EFI intake, after plugging the injector bungs with rubber plugs just to try the fitment and assembly of the engine out. then I sent the heads out to have the valve size increased. The shop unfortunately has been quite slow. Will post when I get things back here.

 

Okay, so I read this whole thread and I still have a questions. These heads on the F500/F700's, are the trucks EFI or carbed or does it not mattter? This may be a dumb question, but I honestly don't know, and if I go looking for them, I don't want to buy the wrong thing. I don't doubt what you say is true, I just don't want to get the wrong thing.

 

keeping this one alive.
