NZ Hot Rod Mag did a couple of articles tracing the history of all of the Ardun heads known to be in NZ. Been a while since I read it, but it was pretty detailed so would probably have some info on what happened to these ones. Sorry, can't remember which issue it was in without digging through them all - maybe Greg can help?
I got all the info from the Hot Rod mag articles and started to update and check some of the stories, sorry got a bit side tracked as it led me to some information I needed for my Stockcar books. Will try and get back to it soon, or at least post a bit of basic info from the articles which of course are copyright and can't be reproduced here.
Steve, did you see any Ardun parts when you were doing your recent Hot Rod book? Great book too, by the way.
