I like that word Bob. I use it all the time.
But, they shouldn't be "that" rare. Stahl has been making headers off and on for years for the "new" nostalgia drag cars that keep being built, even some "street" cars with big ideas. I'm just trying to save the $700.-$800. a new set costs by finding a used set.
The common belief with '09s is that "bigger is better". It isn't true, but don't try to tell that to the guy who just gave Lamar Waldon $30,000. for an engine. The engine I'm planning won't be bigger than 424cid, but I'm going to buzz it.
