It's my job to know what diesel head gaskets look like. It's basically like have the fire ring instead of being on the liner the ring is on the head? So you just use a standard head gasket with them? I know my motor has no liners i'm just using them as a reference.

 

I'm really confused by what you said. But, yes, with O-Rings you use a standard head gasket. You know what a regular gasket looks like, so you know what the fire rings on the gasket are (they surround the cylinders), with O-Rings, they clamp those fire rings down harder.

A fire ringed engine uses a wire pressed into the head and block and eliminates the fire rings on the gasket via cutting them off with a water jet.

 

when my brother-in-law blew his head gasket we took the head to haisley machine and they fire ringed it but only cut the head. and the gasket is a stock gasket that was put on a flow jet machine to cut the factory fire ring out, and in place use a type of metal ring in place.
here is thier link with prices and info. pretty good prices too.
Gaskets & Studs

 

While you can cut the block for Fire Rings you don't have too. You can cut only the head if you want to. Personally I would cut them both but I've seen it done both ways.

IIRC most people are running .041" wire with .012-.015" of protrusion on O-rings. Fire Rings are considerably more of course.

 

if you were doing a complete rebuild (striping down to bare block) i would cut both, but if your not going to that extreme i would do just the head. but before you do just the head have your deck checked for flatness i was told that it is desired for the deck and head to combined to be with in .005" which is much flatter the factory spec

 

well when it warms up some im going to pull the head and see if there is any thing trashed and how bad that will decide how far my rebuild goes. for the for see able future im no planing on running over 60-65 lbs will oringing hold that? how flat does the head and block hove to be for orings?

also this is going to be my daily driver/heavy hauler for a while so i dont want o do anything that will take away from its streetablity

 

o-rings will support 60-65lbs with head studs i do know that, the block and head should be relly flat for clamping purposes
