my 81 AIRCOOLED has a cylinder head temp gauge installed by the PO.

The sender is screwed into the head by the number 3 cylinder and the wire
that comes from it goes to the gauge up front.  Looks right, but generally
shows 150-175 degrees.....reading about the senders at THE Bus Boys site, it
seems that they say something about a sender theat attached to the spark
plug, and that 350 - 375 degrees is normal temp range.

I have fiddled with the timing on the car in the past, and noticed a slight
change in the gauge, but no where near 350 degrees.

Any thoughts, and or could someone take a pic of their set up on their
motor?
