Question I have is what water temps should I see with a infared gun at the upper radiator hose and lower radiator hose.
I am seeing 180 deg+- 10deg at top 140 deg +-5deg bottom after 20 min drive.
I see members saying get a infared gun but no real numbers to look to strive to.
Thanks

That is an often quoted test but in reality, it means nothing.
Is your ignition timing correct? A retarded timing will cause the engine to run hot.
