The reason to cut between the flange is not to prevent warping, but to allow expansion so it doesn't crack (as fast...hehe).

You should also enlarge the outer bolt holes so the flange can move a little on the studs...

They are decent manifolds, for performance and price...but will be a pain when you have to pull it to get it welded back together.
