Hi Christian.
I can`t see the reasom for sealing the bonnet edges, this will increase the heat soak in the motor causing vapour lock in the carbs. Remember these machines where made at a time when the roads where less congested, speeds where higher keeping air flow up. Running these engines on unleaded fuel makes them run hotter. The point about the temp gauge is somthing I found some years ago on a Aston Martin DB3S, the kettle boild and the gauge read 75c, the owner swore blind he neverraced it above 85c, hence flash over heating of the pistons.
