Cylinder Head Temp Variation

[John S]

Ok, here is a thermal image I took today on my engine. The engine is at operating temperature so the numbers should be pretty stable. I am not going to go into any detail here because I want to ask some questions in a seperate post but I think you can see from the image that temprature varies from tube to tube but the center tubes do not appear to affect each other to any large degree. As far as average temperatures, i think it will take a lot more data then I have to come up with anything definitive but I am sure the information is out there somewhere.
