not a 351, but 302 problem i need answered

[red93gtSmokin]

Here we go, i got a 93 gt, brand new 302 short block with modifications the rest of the way out, but at 2600 miles, it started blowin smoke bad(burnt oil). I therefore ran a compression check when i found oil on spark plugs, all cylinders fine! Runs and idles like a champ still, blowin smoke like mofo! ok then oil in puddle in upper intake? has pcv valve, dont know what it could be with that much oil. Is it oil control rings you think that didnt sead all the way, or maybe valve guide seals but it wouldnt smoke that bad and let that much oil and they were brand new afr 165's so any answers please would help!
