big block headers

Those are definately van/motor home headers. Pickup headers look like A body headers in reverse If you look at a body headers the drivers side front tube drops down under the steering link and the Pass side kind of goes back like a Y and drops behind the steering link.Truck headers have the front tube on the pass side that drops down and the drivers side goes down like a Y. The other way to tell truck headers is to look from the front because the tubes sweep in real close to the block. A body headers go straighter down. These center dump on both sides and the are probably van/motor home. You could always flip em upside down and make some zoomies out of them.
