Was suggested to mill the flange to a different angle to pull the flanges closer to the block. Gotta figure out how to clamp the manifolds good and solid in the mill.

Sid, when we first started on the manifolds there was a cover and a EGR on them, but welded and sanded them smooth for the heat coating we had placed on them
So maybe they are Camaro!
