Smoking 273, opinions?

if the valve guides are worn,the new seals can only do so much. I dealt with that this year -I had the similar problem with my right bank. i half fixed it to patch it up,got tired of the "Dude! You're really smoking!" comments ,had a set of X heads built.bought a short block318 and now just wait til Springtime comes to this damned Yankee town when I can beat the piss out of this thing. "Test" drives have already made me see tire smoke instead of engine........................
