I've been told that the 16 valve head was only offered on the 740 for the '89 & '90 model years in the U.S. Is this correct? I have some reference material in front of me that indicates it was sold '89 - '92 and also on the '92 - '93 940. Yes, no, maybe?
I'm trying to figure out just how rare this head is in the U.S. - I've yet to find one in a junkyard. Does anyone have an idea how many were sold here?
Also, is it true that Porsche and Cosworth provided input on the design of this head?
Thanks,
Brad
