Oil control rings can definately contribute to the problem. As well as bad sideseal clearance. A rich tune/flooding can contribute as well.
On turbo cars this is very common, due to positive manifold pressures and richer mixtures under boost.

It's normal for some gas to get in the oil no matter what, but this sounds like more than normal for a non turbo. I don't remember if you said it was ported or not, but some porting styles can contribute to this(the ones that go into the oil control rings).
I wouldn't be too worried, maybe consider running a higher quality oil and change it more often. I change every 5000 km and run mobil 1 15W50. Mine comes out black and smelling like gas every time, as does most turbo rx-7.

They'll send you a free "kit" to put your sample in. You just send it back with oil (3 oz. or so) and $22.50. A couple days later you get the results.
