Alum. Head for 226-254 flathead 6cyl.

What is a good Cyclone or Knudsen Aluminum head for a Ford flathead six 226 or 254 going for?

 

saw a knudsen head for sale on s.f. craigslist last week for $650

 

I know this is sort of an old post, but, im sort of a dreamer.....
Still any leads on the Knudsen stuff?

 

Two years ago I paid $200 for a Knudsen but I had to have it welded and milled where someone used a hammer and srewdriver to take it off of an engine. For or five years ago someone in Georgia had a new Nicson (I think) in a box for $800.00.
