Are they both 1968?

A couple of places to check if it actually is getting hot are: There is a small horizontal hole at the top, accessed by removing the flat exhaust cover plate. It is only about 1/8" diameter (guessing) and easy to get plugged up by trash. Also, there are passages at the powerhead base that get plugged by corrosion (probably more of a salt water thing, but who knows?)

I’d check the cylinder temp instead of the head. The head gets pretty hot because it is only cooled around the edges.
