OK,
I just picked up a used head that I am going to have rebuilt for my fj40. I believe it is off a 77. My vehicle is a 76. On the believed 77 head there are six sort of injection ports right where the intake manifold hits the head. On my 76 I have screw in blockoffs (with square heads for removal) at these locations.. my question is what are these little ports (something screws onto them because they are threaded at the end)? Each one goes through the head into the intake ports right near the valves. They are obviously removable with a socket or box end wrench, but will my 76 blockoffs screw into the same holes? I have no idea what I am looking at, so any help would be appreciated..
Mike
