Don, Thanks for posting that Ardun link cool looking at an add from when those first came out. Funny thing about the Ardun Flathead conversion that I didn't know, and that only the Intake Valve was moved to the head. Wonder what the price was for those "back in the day". There is a Hot Rod shop in Southern Ca selling repops of the Arduns today Sakowski Motors there price today $17,500 a pair.
