I have a 1937 21 stud engine with cast iron heads. Neither of the heads has a part number, but one head has a single tapped hole for the temp sensor and the other head does not have any tapped hole. The tapped hole faces to the rear when the head is mounted on the left side of the engine, for the temp sensor probe.

Up to, and at least on my early 39 Mercury (Oct 38 Production) your tapped head set up would be correct as you would have only had one temperature probe for the gauge in the left head point rearward. AS you see on my Mercury it is pointed forward for some odd reason on a 6050 stamped head AND I believe the 6049, 6050 may have started with the "39" model year!!! I believe the "dual" temperature probes (Both right and left head) started in 1940, for sure in 1941.
