When Is Hot Too Hot?

mine never goes over the third marker on the gauge and that was yesterday in 95+ in bumper to bumper traffic ., yours is on the fifth . Seems a bit on the hot side to me(over 1/2 way on stock gauge = start to worry imo) , but I'm no expert . I would get another gauge to check actual temp . 190-225 is all right , 235 above and it's time to have cooling system checked .
I have 30 over 10.5-1 pistons cam a touch less lift than yours close to stock converter 3:73 gears , hedman tight tube headers , air gap intake with factory rad shroud and clutch fan . Running 50/50 anti freeze water .
