I'm going to be port matching my GT40 heads to my Trick Flow intake and headers as well as cleaning up my headers and porting my lower intake manifold. It's easily worth the time since i'm in there and i recommend it for you as well.
Think of it this way: Do you want to spend some time getting FREE horsepower AND torque at all RPM ranges.
take the time and do it, YOU WON'T BE SORRY! Just make sure that you don't grind too much in any one spot and grind about 1" up into the port minimum. good luck,
