how much smoke and what color? you say not "extremely horrible".. so that means pretty horrible, kinda horrible, bad, so so, a bit?
id say everyone is being a bit passive on the issue because it could be valve seals/guides or just running rich, etc... if its just a little bit, then I would say your okay but if its pouring smoke out the back, id say you have issues.
before my motor rebuild, my car was dumping smoke out the back at WOT and a bit at idle.. my valve guides were bad.. after i had the engine and heads rebuilt, and retuned, I have no smoke what so ever. at idle or WOT.
