We don't carry finished headers but have the components to build your own. Check out the website:
www.coneeng.com We just helped out Fuller Hot Rods with a set for a 572 crate motor. 2 1/8" primaries into a merge collector. You can see the car being built on 2 Guys Garage this fall.
And if you can't build them yourself we are building a referral listing to help you find someone to help out. If you know of a good builder let us know so we can get them listed.
