the thermostat to 160 how can you tell if the thermostat is open
Not for sure, but 195 sounds right - 160 is definitely too cool.
The pressure on the heater hoses will be the same as the rest of the system - 16psi or so - whatever the radiator cap is rated for. It's important to keep the proper cap rating on - this raises the boiling temperature of the coolant.
As ProjectSHO89 suggested - check the heater hoses - both should be hot.
One item of experience from my past is that I bought the cheapest heater core the parts store had. It didn't heat well. Closer inspection (held it up to light) showed that about 1/3 of the fin area was blocked off - not apparent until looking through the fins. Heater wasn't heating well, defrost was a lost cause until I got a good core put in - then all back as it should be.
Your vintage likely still uses a cable to actuate the blend door - do you hear it 'thunk' closed when you move the controls to Hot?
Are you sure you have enough coolant in the system?
