Thanks to all for the advice regarding the heater core. If worst comes to worst and the core is completely shot, any thoughts about whether a traditional engine radiator shop can re-core it, or how I would go about sourcing a replacement (I've never seen anything like this come up on ebay).
Thanks again, Lance

I might as well tackle mine as well, disassemble and rebuild.
Thank you Charles

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.*
