O ringing a block without a reciever groove in the head to accompany it does not gain very much.
I've been running O rings for years, mainly on my old AMC engines with very high compression, and which had a very poor head bolt layout. ...but that was before the availability of MLS type gaskets.
O ringing is not legal for Stock eliminator, but I think it's been legal in SS for a few years .
BTW ,according to the manufacturer ,you can't use O rings with MLS type gaskets.
I only used them with copper gaskets.
