Fire rings are usually only used in competition trucks running crazy timing and nitrous. They tens to have leaky water jackets and the like. Also, compression is routinely lost to the surrounding gasket and even into the engine. Fire rings are cut into the block and the head as receiver grooves for the rings. And the fire ring in the gasket is then removed.
O-rings are cut into the head surface. A wire is inserted and this applies pressure to your gaskets fire ring. If installed correctly, they are very effective and don't have the leaky tendencys of the fire rings. Around here, O-rings are $200.
If you O-ring or fire ring, skip the stock bolts and go to studs! Do lots of retorques or you will lose the gasket.

$200 per cylinder? If that sounds like a good deal, I'll pay shipping both ways!!
It's $200 for the complete o-ringing job. Head surfacing is a little more an I have yet to have a head be completely flat. Also a great time to do a valve job and I can assure you the exhaust guides will be shot.
