temp gauge tuning

Hi
Just got a cheap temp gauge 10mm too small to fit on the spark plug. Would placing it under one of the head bolts still give a accurate running temp? What temp range should be looking at achieving.

Greetings:
I ran mine under a headbolt for a couple of years. Temps seemed the same, plus or minus 20 degrees. Added advantage of not having to screw with the wire every time you pull the spark plug.

I have the same but I'm only on a 86 main. Is yours ported. Every seems to be using much larger jets than I. If I put a 92 or higher it spits and is slow of the start with the odd back fire.

380f is about as high as you should go.Ive seen spikes of 410f and no damage but i dont recomend it .Keep it between 330f and 380f .
