Re: O-ringing an engine???
O ringing is where a circular groove is cut into both the head & block,on each cyclinder
Felpro loc-wire head gaskets use a groove or receiver ring cut into the head only for each cyclinder
The gaskets oversize wire rings locate into the heads receiver ring. creating 2 combustion seals, the primary seal is a result of the clamping force which squeezes the armor covered wire ring between the block & head, the secondary seal is at the outside edge of the groove
These really are the $hit when it comes to containing high combustion pressures.
