The 2531894 head ran into the 70/71 model year depending on what you read.
If an X headed 340 made it to 1971 production it's one in a million.
915 J heads were the primary head in 1970. The X heads ran early in production for 1970 and I've seen some December 1969 build cars with them, but they are not the norm.
