For the long time reliability I'd go with Astro. Have one in my 940.
Short term- remove the valve and install a piece of pipe in it's place. Or bypass the heater core all together.

Same as simply disconnecting the frequency valve. You may want to check/dial in the base CO level using gas analyzer. The Cat will likely be ruined in case you are still running it.
