Baron, mine has a lot of options on it - this may take a while.
When I PHS'd mine years ago, all I got from Fred was a hand written note on the cover page that said "Nice Car!" I bought it not knowing the difference but found the II motor (now motors) for it so I decided long ago, that's how I'd build it.
Head casting update - I've found a set of C288 heads, trying to get pictures to confirm.
