Nice 3-stage header. Or is it 4?
You’re a rare breed JTSD. Most people like yourself are afraid of the ol’ flatheads, just don’t understand them or hate them for no good reason usually.
It's not quite either. It kinda bottlenecks right after the flange, and then about 4 inches along it expands for about an inch before it hits the second stage.
I think it's a tuned header!
Thanks Hellion! Yeah, I've heard people complain about the flatheads, like "Oh, but where would I get parts?"
Ebay, Amazon, Outdoor Power Direct, ereplacementparts.com, Repair Clinic, DynoCams, etc., etc....
They're everywhere.
And they're super simple engines!
I've kinda always had a fascination with old engines. Whether it be classic cars or go karts!
