I am going stock exhaust manifolds for my 273 with manifold back dual exhaust. To that end I detailed the castings by removing all the superflous material and doing a bit of dress up with my air sander. I removed the heat risor butterfly from the passenger side and brazed the holes shut. Then I took them to my coater and picked the color you see here. The engine will be painted body color with black accents so I think these will look good and correct. Total cost, $4.00 for sanding discs and $100.00 to coat.
Leaves me some cash for other needed things-:)
