Contact Jerry M and ask him to put a straight edge across
the flange surfaces. If they are problematic, ask Jerry
to get them fly cut.

Steve, I can't imagine why it cost you that much money to
get the 455 manifolds cut. It's a flat surface and somewhat
easy to indicate for flatness. Then, you just take a light
cut for cleanup. Unless I'm missing something, a skim cut
should be fairly easy to do. I will have that done to my
manifolds before I install them. 30+ years have to account
for a little warping I would expect.
