66 dart headers

Doug's makes a set of headers for the smallblock in the early A bodies. They're $819.95 from Summit.

Suregrip 391 (?) had a buddy that was selling Doug's headers for less, somewhere in the $650 range IIRC but that was maybe a year ago & I don't know if he can still get them. You might check with him.
