You know you got an EARLY head when...

Sounds like a joke, eh? Well, its not ...
1. There is no bolt boss by the thermostat housing for the "passenger side" alternator tensioner.
2. There is no bolt boss next to the #1 plug hole for the 3 bolt alternator base to bolt up to.
3. There is no "countersink" machined into the face of the threaded plug holes, its unmachined (STILL needs washers on plugs)
4. Your valve cover has 2 "stacks" instead of one and a PCV grommet.
5. Your valve cover is mostly flat across the top.

Some of this stuff says 60-62 but I didnt see a date on my head. Just an FYI if you see a head at a swap meet and want to replace your 63-73 head and expect everything to bolt up identically.
