Smokingwheels,
Some info from another site discussing engine temps on MG B's which may be of interest.
"All this high temp and ceramic paint talk has me baffled. Just how hot do you expect these things run??
Here are some temps I did to answer a question last summer.
Jeff
Here are the readings I just took with a contact themocouple, rather than infrared.
1275, at operating temp, idling after a 10 mile drive.
All temps in Fahrenheit, surface temps only.
Top of head at thermostat housing: 163.1*
#2 stud at intake/exhaust manifold: 186.3*
Exterior of exhaust manifold: Front: 289.0*
Center: 290.1*
Rear: 287.0*
Intake Manifold flanges: Front: 163.2*
Rear: 167.4*
Head at rear exhaust manifold mating flange: 220.8*
Head at #3 plug: 158.8*"
By the way Piwoslaw's suggestion of an IR temp sensor is a good one.
Dick Smith , Jaycar etc have them in various grades and accuracies for not a lot of $.
Maybe you can borrow one for the weekend if a long term use is not needed?
Peter.
