What the yanks do is put the better flowing 20R head on an early 22R bottom end to make a 20/22R hybrid. The 20R has smaller valves etc though, and won't bolt up to an EFI manifold without some welding/tapping... Apart from the fact that, as Viper says, we never got the early 22R (you CAN put a 20R head on a late 22R block if you mill the head down a fair bit), I'm faily sure out 21R head does NOT = a 20R. (Not sure I agree with the 22R having roudn exchaust ports... I thought it was only the 20R that had round ports, and these are normally ported to suit an EFI manifold) [Report message to a moderator]
