273 Buildups - Status Checkin

"quick valve job and check the guides " good luck with that. Those heads didn't have harrdened seats so you may find recessed seats, razor sharp edges on the valves too. Maybe not. Just depends on how long it ran on unleaded fuel .
What cam did you choose ?

Good point. The machine shop should catch all of that. What do you think is better, hardened seats or stainless valves. The guys at the machine shop that
will do my heads recommended just stainless valves. I only drive a few thousand miles a year and the stainless valves flow better and will last a long time. I've heard some horror stories about replacement seats falling out. What's your opinion? MIke
