I am looking to have an engine built and was told they will have to ring the cylinder heads
 
Did you just hear them wrong and hear ring when you should have heard ream?? Reaming the cylinders means that the cylinders don't neccessarily need to be bored, so what they will do is use a ridge reamer to remove the overlapping cylinder wall from where the piston reaches it peak to the top of the cylinder. Then they will most likely just hone the cylinders unless you want boring done.
 
No, they said to ring the cylinder heads...
 
They could be talking about installing seat "rings". In other words, installing hardened exhaust seats. They are also called seat rings. Ask them to explain what they intend to do and why before committing to it. A good shop will explain things to you. I was a machinist for 10 years and I never had a problem showing customers what I was going to do (or was already doing) to their parts.

If they actually said that, run like hell and find another shop. Personally, all I've ever heard valve seats called were valve seats, so if that's what they're talking about then correct them. It might prevent them from calling pistons "slugs". God I hate the use of bad terminology. Yes I realize that our friends across the pond have got some really bizarre names for things eg. spanner and notched nail.

only thing i can think of is to o ring the block and heads where thay cut grooves in the block and head to o ring seal around each cylinder but that is usually only done on high horsepower engines and i think only when running lots of nitrous id agree with demonseed may want to look for another shop if your not building a really bad *** engine.
 
You may have hit the mark because I am planning to supercharge this engine.

that may be it you need to ask and get specifics on what they are talking about but you usually only o ring a fairly high performance motor when you are introducing higher cylinder pressures in it like nitrous turbo supercharger etc. but i would ask the machinist and make sure of what they are talking about before you give them an ok to do any work. Hope that helps if i am even right Justin
 
Yes its O Ring. They cut a groove in the heads and run wire around it to help seal the cylinder.
 
could we know what your proposed build will be?
Iron head or alum?
 
Ooooh, a supercharged Mopar! I always get giddy at the notion of forced-induction Chrysler V8's. And yes, they probably do mean o-ring the cylinder heads or decks. BTW, I should tell a buddy of mine on Moparchat about this...
 
blower or nitros,,,on a small block mopar require O-RINGING,,, i have an groove cut in the deck for an 043 wire,,and i also use the felpro permatorque head gasket,, it has a ring around the cylinder built in to the gasket also,,

some shope will do a groove on both the head and block as a reciever groove for more positive sealing,, a standard production 340 still may have head gasket problems being O-RINGED if you have to much boost,,the race blocks or the earlier version called the " X " blocks are more stable and thicker decking to leson this problem,,,,, i have an " x " block,,superecharged

Ahhh...that's a key piece of info you left out in your first post. I'm surprised they used the term "ring" the heads. The term "o-ring" is widely used. Sounds like a cool build. It would be interesting to hear your plans for this engine.
 
Depending on how much boost you will be running MLS (Multi Layer Steel) headgaskets will work just fine and you won't need to "o" ring the heads or block. I am running MLS on my 340 with 270 psi cranking pressure (14:1). Been in the motor 2 1/2 years with no blown gaskets yet. I am also running studs.
