340 no Heat control valve not working and no power brake assist

New owner of a 1973 Dodge Dart Sport 340 H code.

Feels like there is no power assist with the disc brakes and the heat control valve does not work when temp is set to heat it just blows cool.

The vacuum hoses are as follows:

Hoses from the firewall:
Green stripe vacuum hose cut and looks to be plugged with a tube.
Black hose goes to the vacuum amplifier but connects to a vacuum T that splits going to the heater control valve and the other end to the vacuum amplifier.

Large hose from the Vacuum Amplifier to the Y connector on the intake manifold and the Y-connector shared with the brake power booster to the check valve on the booster.

I am assuming this is causing both issues?

Thanks,
Eric
