GT40 heads

[fratzke7]

Hey guys I recently purchased a 93 notch that has a 306 with all the GT40 goodies and pleanty of others. The question I have is that how do I tell if the heads are GT40? I had a friend look at them and he said that his GT40 heads say GT40 right on them and we didnt' see it on mine? Any help would be great!
Thanks

THE GT40'S DO HAVE LITTE GT'S ON THEM AT THE FRONT CORNER OF THE HEAD WOULD BE THE EASIEST PLACE TO SEE THEM AND THEY HAVE 3 VERTICAL LINE RUNNING NEXT TO EACH OTHER ON THE FRONT FACE OF THE HEADS.

don't be fool'd.....cause GT-40 P's have the same lines only they have 4 lines....3= GT40's 4=P's

Real GT40's spark plugs go into the head at a 45 degree angle, GT40 P's going just about perpendicular into the head. P heads have a P on the bottem right when looking at the passengers side head.

Ok well my spark plugs do go in at a 45 degree angle so are there any other heads that have plugs that go in at that same angle?
