    Can/would you resurface these 455 manifolds? I imagine an engine builder would surface them like they do to remove or true the surface on a head?

    The machine shops locally will just stick them on a belt sander to clean up the surfaces.

    Yes.
    Only have the minimum taken off to provide flat and parallel surface that will seal effectively.

    Belt sander better. I had some done on a milling machine and they ended up cracked.....

    Did mine on my milling machine. No problems since I did them in 2017. Also trued up the heads. No gaskets. No leaks. 71 455.

    They have no control over what they are doing. This is the way to do this job:
