If you haven't started your truck since replacing the heads, it is possible that the other head has that hole drilled and tapped for the AC bracket bolt, and you can switch the heads. Not sure about an engine of this vintage, but in later years, heads seem to be made to be interchangeable, with holes drilled and tapped everywhere. Given that GM tracked the cost to .1¢ for parts (when you buy millions of screws, for example, it makes sense), my guess here may be wrong.

Good info. The head in the pic. is the rear LH side. Didn't know you could swap some heads. Perhaps it was the A/C bolt.
Looks like I missed a stamp.

Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
