G'day HP,
the casting # should be on the back side just above the inlet manifold.
The rocker box will have 67-280 cast in the underside. It's a std. If that # is over stamped it's for a SR.
Cheers

Don't know what the 18AQ means. Looks like a PO has polished off the casting #'s. Check the diameter of the comb chamber and inlet manifold.

The head number should be on the bottom side of the manifold.
