My stock heads had bad valve seals. Not too bad,just a little smoke when first starting up. I wasn't in a rush to replace them.But aquired a set of 202 fuelie heads from a long time friend. Couldn't pass them up.They are remanufactured.Never used.Had the motor apart and back together in our barn in 12 hours. Higher compression heads killed my starter.Had to get a new one. Was backfiring and turned out to be a cracked plug.Today i took my Camaro to a carshow,first time since head swap..He sounds and runs great!! I think even better than before!! Here's a few pics...

Engine apart...also put in mild cam,but didn't open front yet in this pic.
