MG MGA - Matching ports

I want to match the ports on the cylinder head (MGB) to the manifolds (MGA). The inlets match OK. The exhaust ports in the head are 1-3/16 deep, whereas the manifold ports are 1-7/16. This means there needs to be 1/8" opened out top and bottom of the head exhaust ports.
Is it OK to remove this much? Any danger of breaking through to the water side? I was going to slope it back about 1"

You should be able to match ports for that much material. You can shoot me or take my first born if it doesn't work.

Thanks for the advice Barney. That's a very generous offer, but I'll let you off the hook!
Seems like such an obvious item to do, I've not heard it discussed. It is obviously more than just a casting tolerance, BMC must have had something in mind for the future?
