Reply to "180 degree headers"

These headers were purchased as being for A3 heads. So as far as having to adjust for higher exhaust flanges, no. That was already built into them.

There was one problem with them and that wasn't caused by Halls builder.
The problem was that Ford Motorsport (now Ford Racing) changed the lower bolt pattern on the heads from what I had.
I guess mine are early A3 heads, I don't know.

The simplest thing to do was to redrill the flanges on the headers and use flat washers to cover the inequity so to speak. That worked out fine. I also got $100 credit from Hall to do this, so I was ok with it.

Also, but hardly work mentioning, I think tube #6 had to be flattened to clear the gas tank shield.

Other then that, they fit very well.
There are no horror stories to tell about them at all. They fit pretty well and are sturdy.

They supplied asbestos gaskets for them but I found it easier to make new ones out of 16 once copper sheeting. It is soft enough that it works well as a gasket material.

I'd like to get them jet coated eventually. That's just another $400. I may also replace the bullet pack mufflers with polished stainless ones also so they function as exhaust tips. I can get a 45 degree radiused tip on them which will be about right to center them in the stock cut outs.

All in all I like them with my setup. A3 heads, Webers, solid lifter cam.
On the open road they are no louder then stock and they really sing at rpm.

I think you will like them.
