Temp readings higher on port side

[kellydee]

About 20-30 degrees higher.Can anyone tell me if this is normal or maybe to do with the steel tube that runs from the port exhaust man. to the port side of the intake man.?All temp readings(IR gun)are higher on the port side of the intake. 2007 Merc 5.7/Alpha. Jerry

What does the water temp. gauge tell you... what makes you need to check it with an IR probe?
