Porting a TPI intake manifold

Anyone tried porting the intake manifold on a 305 LB9 motor? The intake ports are quite a bit smaller then the ports on the cylinder heads. I'm trying to match the ports but I'm afraid to take too much off the intake manifold side of the ports. Also, the fuel injectors drop into the top part of the intake manifold.

Do a quick search. Porting has been discussed many times.
