Well, I've tried to search for this on the forum without success. I know it's possible to bolt on (with a lot of work) the head from a BMW K series engine to the A series block, but unsure whether the head I've come across would be worth pursuing as a donor. It's from a 1989 K100RT, and it's an 8 valve head. What I'm unsure about is how much of an advantage this would give me over the Stage 2 (I think) 5 port head I have at present, or whether I should try to track down the 16 valve version (and I'm not sure which BMW had this head, although I'm guessing it would have to be a K1200).
Anyone have any ideas, or better still, experience of fitting the BMW head?
