Why are my dougs 450 headers hitting EVERYTHING on my early a

I actually tried that first but wasn't enough room near torsion bar/frame to put three tubes . If I would have wen on the other side with 3 and 5 I would have had 4 slip fits and would have been difficult to get header out. Its super easy to get out now.

I have thought about adding a slot between the 3 and 5 pipes so they can share the tubes at the top like a manifold then follow down as a separate tube after the bend.

Plugs look real uniform, I'm sure I'm giving up a little performance and even cylinder evacuation but they are super easy to put in and remove with motor in and I'm only running a built 273 for now. One of the 1-3/4 tubes is about the same size as the outlet for the stock manifolds haha
