Lingering fuel smell in oil

Thanks for the input guys. Got a few more things to look at, it appears.

Drove it into work today, taking the 'long' route so she could get up to temp. Had a few minutes so I pulled the PCV. Clean (had replaced it not long ago) with good suction. Shut her down and peeked into the carb to see if I had some dribbling, but unfortunately the sunlight angle was wrong and couldn't see much (no flashlight with me). Will try again later....

I'm in the process of collecting parts for the super six upgrade, so if it ends up being the carb maybe this will give me the kick in the pants I need to get moving on that.
