As far as I know the PIM manifold is made in Australia by a company called TFC. The pictures of the manifold in PIM's ad are quite old however. They've been there for more than a decade. That is not what the current TFC manifold looks like. Check out the pics in the link.
TFC at Aus Ford Parts. PIM's price is fair as long as they are selling the current version of the manifold and not an older version.
I've known a few people who've used the TFC manifold
with 2V heads over the years, everybody has liked it in that application.
