Alloy Head ID 18AQ ? rocker box 67-200

[Humble Pie]

Have an Alloy head the only #'s I can find on it are on the left side below the valve Stamped 18AQ.

No casting #'s or stamps

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

ok rechecked

its a 67-260 on the box  but still nothing on the head

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.
Cheers

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