Slant 6 intake/Exhaust Install

What are you guys typically paying to have your /6 manifold milled flat? I need to have that done myself. I would have adjusted but my INT/EXT mating bolts were just about locked solid so I took a chance and put it back on anyway. Lasted about 1000 miles before the leak got really bad. I've got to fix it before putting the Dart out on the road again for the year.


I paid 45.00 for mine to get done , but I got a super good deal I think. I've heard anywhere from 30 to 100 for it. And it depends on if you get the heat pocket milled to bring in the up/down alignment. I didn't need that but I went through 3 manifolds to get one that fit good to the dual 1bbl offy manifold. Of course now I'm going to be using "Waggins dual setup" so I'll have no alignment issues at all on the one engine.
