Reply to "Overheating"

Thanks guys. Took it out today to check fans, temperature, etc. Drove about 15 miles at about 50 mph, back roads with outside temp at about 75F. Temp gauge rose to about 195, then reversed course and settle in just above 190. Stayed there through some stop and go. Stopped to fill the gas tank, drove back the same route. stayed pegged at just above 190 the whole way back, until i stopped in my driveway to check the mail, then it immediately started to rise and headed straight for the edge of the red zone.

Checked the fans, all three were running. Hit it with the IR temp gauge with these results:
Block (backside) - 218F
Heads - 198F
Surge Tank - 180F
Radiator top - 185F

I do not see the gauge temp sensor at the surge tank, so it must be on the front of the block, hopefully near the Tstat. Here's what my surge tank looks like, i think the neck has been cut down already for a US cap??
