Ok, I have read a lot of things on flathead overheating. I have a 48 Fordor sedan running a mild rebuild with mild Isky cam 3 on the tree, 2 bb l(jetted for the elev 5000ft), dual exhaust, Pertronics ignition, Converted to 12v. Alternator & Vintage Air. New Alum radiator, 160 deg thermostats & 4 lb. radiator cap. Runs great but will get to 212deg and way past that on a grade. I do not(can't)run the air.
1) How hot is hot on a flathead?
2) What can I do to keep the temp gauge from becoming my stress gauge?

Any help will be really appreciated.
