What kind of pressure are you seeing? Typically I'd say anywhere around 20psi increasing to around 40ish at cruising.....60-80 at redline would be a safe range for any motor. I don't have any exact "5.0" numbers, though to help, sorry.
i teed off the where the factory sending unit was. warm idle 34 lbs and 65 lbs cruising. using speedhut legacy gauges, water temp runs around 185 without running air and 190 with air on. if you don't know about the speedhut gauges you need to ckeck them out, they come in about 3 levels, i chose mid grade over the base because of better sending units and you can custom build them to your liking for the same price.
