special tool

I would like some input/estimates on possible cylinder barrel temperature at the top 1 inch of the barrel.
I know what the water temp range in that area is, but I am interested in the higher temp of the alusil as the heat radiates through it under boost.
Thank you.

How would you even measure that?

You could put a Sticky thermometer on in there next time your head is off, and then just string the wire out the water junction hole into some sort of coupling on the hoses.

Here's a nice little read on a test: http://www.luxtron.com/pdf/AN88-EAS100-03.pdf
