Okay, thanks!
So would it be safe to assume that if the head temps reach a critical temperature reading., that the engine oil temps would reflect that?
I’m sure the answer is yes.
And for that reason, I have to ask that if oil gemps are high, then it would be safe to assume temps at the head would also be high?
Again, I would expect this answer to be a yes too.
So then why go through the trouble of checking head temps when a simple analog oil tank cap would do the same?

Haven't read through the thread or what is trying to be accomplished - ( I just dropped by because I hadn't heard from Schex in a while ). If specifically looking at temp to reduce wear - lube breakdown - warpege - tuning to reduce temp for a reason unknown to me IDK. I know Schex is a wrench/Tech by profession, so there is value to tracking the specific area temp. I'm just a guy who likes EVOs because they sound good and are almost bullet-proof.

The best way to sense combustion chamber temperature is a probe right in the chamber. Since that's not very feasible, nor would it give accurate temps with is extreme fluctuation between combustion stroke and intake stroke, the common methods of temp sensing are EGT and cylinder head. I've go the EGT port in the exhaust 3" away from the head, and now I've got the spark plug thermocouples under the spark plugs. I've read that under the spark plugs is the best place to sense head temps since it's hottest right there.
If you look at engines in more critical applications, like small aircraft, EGT and cylinder head temp gauges (read under spark plugs) are common instruments in the cockpit.

If one wanted to read head temperature, couldn't I just use an infrared laser thermometer? It doesn't have logging capability, but at least I don't have two unsightly wires on my engine. Plus I now have the ability to measure other points on my motorcycle, like exhaust, electrical circuits, etc.

I have one of those, I use it to measure oil temps for frying fish.
