I'm going to post some gasket overlay pictures in a little while.
After looking at the mismatch I don't see where this is a feasable modification.
In looking at the picture of the manifold, I presume that is cut for a 9.5 block?
If it is, there is no way there is .375" left to mill off of each flange. Even if there is, forget about the bolt holes.
You are going to have to weld them up and redrill them.
The best thing is to convince TrickFlow to build a manifold that will fit a 9.2 Cleveland block with real heads, not the 2v production heads.
The more I look at it, the more I like the EFI setup.
