I believe that the 'overpressure' technique, where the mold is poured and then subjected to a few atmospheres' pressure, would do better than gravity feed. Unfortunately, that requires non-trivial equipment, namely a sizable compressor and pressure pot.
I have more info for you on this. There is a company that puts out a nice pressure pot here in PA. While the compressor can be expensive, the fellas over at smooth-on.com told me there is a cheap solution: use the tire filling station at your local mechanic's bay or gas station. This would be a pain in the rear for the long term but if you are desperate (or don't want to risk buying a compressor before trying your mould) it is a quick solution.
Just remember that if you make pressure casts you need to make pressure moulds too, otherwise the rubber will compress and distort the casting._________________
