Finally got my heads back from being freshened up and reinstalled em the other night...Been slow going this winter, too darn cold and too darn lazy...the 272 looked really good inside, been bored over .40 thou, and didnt really have any ridge. I think someone did a shortblock rebuild without touching the heads. The heads were the good ECZ-G's. So eventually they'll go on the 292 unless I can score a cheap 312. Enjoy the picts....
