There's a bit more info. about the head markings here:

Also, if you're taking the engine apart, consider changing the head studs. Early ones are noted for being brittle and having a tendency to snap. More info. here from

Before I take the heads off I would like to order the studs if I need them, but obviously do not want to order the new improved studs if they are already in there.
