Amen, Charles. I had mine apart twice. Foam gone, vacuum motors stuck...Ranks right up there with disassembly of inboard disc brakes as measured by the universal mechanic verbal metric: profanity/minute! Or per sec.
PS: long ago I bought a heater vacuum valve for my P6, thinking it was the unobtainable original. It is not for a P6; it is an NOS Ranco FHV 2105, I think for a Land Rover. It has electrical contacts and a long bendable thick wire which is probably the temp sensor?   Charles, if you need, I would send for postage only, by way of thanking you for all your kind advice.

Also.....the heater core was originally sealed against the sides of the cabinet/housing....which (foam) sealant has probably crumbled to dust long since. The remedy: remove the heater , disassemble cabinet and replace with 1-or-2-sided foam tape of appropriate dimensions.  Also the cabinet itself may be leaking at its seams, best sealed with black sticky 3M product, I believe it was we just used days ago. (Welcome to call for product name)

A better blower motor, if the core isn't making adequate heat, will only blow more cool air your way, not the desired effect.

Shooting a non-contact pyrometer at (or feeling with the hands) the supply and discharge hoses (engine hot) will also tell its own story.

*Thank you for your enquiry for our parts and services. We offer the highest-quality spare parts for the vintage Land -Rover. Our staff is minuscule while the demand for rare and “unobtainable” parts for early Land-Rovers is relentless. While your concern is important to us, our ability to respond to each and every enquiry may be limited and stocks of many items are critically low.. We are primarily a restoration-based enterprise but when we have a surplus of a given  item, we are able to offer excess stocks to our dedicated clients. If your need is urgent, we encourage you to contact us by phone, in person. Leaving a message is rarely effective, so we recommend direct contact. With many buildings full of parts, it is not always easy to locate obscure items, and the process is often time consuming. We hope you understand. Please provide complete details of your exact model including year, wheelbase, which side drive, engine, Country of origin, etc. When giving part numbers, please also state the catalogue number (typically found on the front cover).  We appreciate your understanding and will do all we can to help.*
