Nothing wrong with those temps unless there is some other problem.

Here's what Stant has to say:

Thermostat Temperatures

Thermostats have a “rated” temperature such as 180F or 195F
This is the temperature the thermostat will start to open, give or take 3 degrees
The thermostat fully open about 15-20 degrees above its rated temperature
Many thermostats have a “jiggle pin” or “check valve” that allows trapped air in the cooling system to pass through the thermostat and be released from the system.
If a Stant thermostat does not have a jiggle pin, it will have a "bleed notch” or other method of removing air from the system.

I've found this to be mostly true. I'm running Robertshaw 180 stats in my 8BA and the engine runs at 190-195 as tested at the heads.

thanks for the replies, no I didn’t test them before I put them in! replaced housings and thermostats because they look pretty bad but they still ran at 180 guess I should’ve stuck with them! never had that issue in my 48 Chevy, always ran true. Going to get a laser gun and checked temp to the block, thanks for the help!
