The repops are over $12K. And who knows what an original set would bring. There are not that many around. Think original production was on the order of 300 to 600 sets.

II met a gent at the Mid-West NSRA Nationals who had a 32 roadster with Ardun Heads and Weber carbs. It had well over 50,000 miles on the clock and had been driven in every state in the continental US. So, even if they don't pump up the horse power much they are reliable and sure look trick.
