A little update. Manifold's back home with me, and I've played with superimposing it on the head. Interesting points:
•The mating face is 31½° off the vertical, inclined towards the valve cover (like the B&W picture of the other manifold). When the log is milled off, that will make reaming those inlet ports to perfection even easier than on an Argentinian head.

Lack of flow will NOT be an issue.
•As Steve mentioned, the current carb size hole is 1½". But there's plenty of meat to ream out for even a 2" bore. XECUTE, I
need your HS-8s.
•The casting is a fairly rough sand jobbie. Unless they include the matching steel plate and good instructions, this Lynx part is now seriously overpriced at AUD$300-plus.
A week and a half should see some photos up; just the clean manifold. I want to approach Lynx nicely and ask for install details. The matching steel plate will likely be jobbed out by an engineering shop down the road. Yes, my engine guys have heard of TC Falcons (not by name, but know of them), do know you can mill 150 thou off a Ford six head (their comfort zone), and have an old-timer who can weld cast like it was made. Some things are good in Sydney!
