I would use the Bosch temp sensor at the front of the head. I haven't checked
the thread but you definitely should. It looks like 5/16"-24 UNF
The thermal time switch is somewhat insulated from the BLOCK which will warm
up a lot more slowly than the head. The hole in the block into which the
thermal time switch adaptor screws is a big UNC bolt thread, probably 3/4".
The adaptor, being heavy steel, will see a considerable temp lag over the
block, which in turn will not heat up as quickly as the head.
