Stuff from Falconer/Dunn was a 'buy out' at end of USA/Can TA series as I understand it. Alloy Cleveland blocks were a 'back door' casting deal @ Ford that had not worked out due to lack of material in webs. A 'well known' Aussie scooped them up before they were -remelted- and shipped them out here and they ended up in PDL Mustang's- Moffats-Sidchrome + others I believe.

The same set of GW heads saw service with all the guys you mention with the Cortina of Kennard/Buckley & Slade had them on his Mustang plus the Capri that was owned by Jim K from the west coast I think. I remember Bob testing @ Ruapuna & couldnt get the thing to go right. He knew he had less than optimum compression ratio & squish due to lack of time to procure/make correct items, so in desperation he advanced the dizzy to give 55° total. It worked, nobody could catch him on raceday. Talking to him later he reasoned that due to the alloy heat flow rates plus the better chamber design of the GW that it was OK. You have to remember that we were running 42° total on popups on Iron Boss 302 stuff in those days so it was not that far out of line.
