Default O-Ring Cylinder Head Specs

Looking to send my cylinder heads to a machine shop to get O-rings put in.
Most people I have talked to are cutting wire to length and lightly tapping in with a hammer. Is there anyone out there that makes one piece O-Rings?

Does anyone have specs for cutting the cylinder head to give to the machine shop? What type and wire sie are people running?

Thanks

Most do the block, not the heads on a Dmax.

As Zak said, most people do the block since the steel gasket already "bites" into the head and doesn't have issues sealing.

the idea can be argued either direction and ive seen it done both ways. Both have worked

Have you talked to you machine shop yet? if this is new to them, think twice about going there.

Who’s fire rings are you using for the block? What size are they and does anyone have specs for cutting the block?
Are the rings you guys are using one piece or cut to length?

Fire rings are different than o-rings. Fire rings actually require a groove in the block and head to seal combustion gasses as well as require a special gasket and uses a solid piece/insert that is measured to the groove cut. O-ringing has you machine a grove in the head or block or both to use a steel wire to help bite into the MLS gasket allowing you to run a standard head gasket and is cut to length.


Are you wanting to do o-rings or fire rings? As said above, if your machine shop hasn't done this then I would recommend you find someone else or you may be playing with fire.

I am running around 900HP and 80lbs of boost.
Wagler sent me some O-Rings that are 0.070' thick and was told to cut 0.063', only leaving 0.007" of protrusion. Does this sound correct? What size wire is everyone running and how deep are you cutting?
I am just looking to O-Ring the head...

Thanks,

All depends on what gaskets your using. You need to the the crushed thickness.

That should be fine. Personally I dont think you even need orings myself at that level.

At what point are guys installing orings . Is it based off a HP# or high boost#?
