That doesn't make sense. The goal of port matching is to match the ports to each other. You want a nice smooth transition from the intake port to the head port. Any steps will create unwanted turbulence.
If the heads are 1262 R, then the intake manifold should be the same.
BUT.... like I said before, many IR manifolds cannot be ported that much. Set the manifold on the engine and see how it fits before touching it. If it doesn't match, you need a different manifold. Been there, done that.
