Probably not a real big deal if your replacing all the internals. The later year ones have a better rear oil flow passage and better crankcase breathing.
Here's a good but outdated website that I learned a lot about LSX engines.

I bought a "core" LS1 block that had a cracked cylinder. #7 had a crack through the liner and aluminum coolant jacket caused by running lean with an STS turbo. Look at #7 really close when you are there.

I agree about it being a bad oil ring, too. The cylinder walls should be spotless and just go over everything REAL carefully. The finger nail suggestion is always a good rule of thumb (or finger)...

$350 is a good deal if it has center bolt heads.
Look around the head's valve cover sealing surface for scratches and nicks. Thats a sure sign that someone's been in there changing valve springs, which means they've had a cam. If they had a cam, then its completely possible they were spraying it and might be why the engine smokes. Most motors will rarely have their valve covers pulled and shouldn't show any wear.
