B20 Cylinder Heads. 140-160 1971

From what I have read, the late cast Volvo twin outlet exhaust manifold is very good. So good that there is no advantage spending lots of your money on a tubular 4-2-1 header. In fact some say many of them are worse than the cast ones. The basic Simons system one bolts straight onto the cast manifold. Probably the sports system can be adapted to match the larger pipe size.
What engines got the F head? Am I right in saying that they only got fitted to the 1 year only B20 engined 240 in 1975/6? Not many of those around and AFAIK those were only sold in the USA, maybe a handful in Japan?
