Has anyone o-ringed the block and run stock 87 head gaskets ( .060 thick ). I would assume that this would require installing the gasket upside down. Is this doable?

Lee,
You mean with a wire-ring in the block around the cylinders? My original motor I took out of my car was .020" over with this setup and Fel-Pro graphite replacement gaskets. The gaskets when I removed them were installed like normal. No problems with them but I didn't really understand the theory because the wire hit outside the fire-ring just about everywhere except between cylinders. Does this help?

o-ring
I/ve run o-ringed heads with 87 gaskets. I guess the theory is for the wire to back up the fire ring. I liked that setup. My friend is building a .020 over -3.8. The machine shop who is doing the machine work can o-ring the block but can/ t o-ring the head. That is why I/m asking

My previous car had the block O ringed as well. The machine shop I use also could not O ring the V6 heads, just the block. I had them O ring it for the OE headgaskets, with the O ring just outside of the factory fire ring to help support it. IMO this helped to keep things alive under some extreeme racing conditions. Don't however think that the block O ring will prevent that fire ring from blowing out. I actually blew a headgasket with the O ring, thus causing the O ring to actually smear out of its receiver grove. This is an easy fix though, just use a pick to pull up the O ring at the union point, and pull it out of the grove with pliers. Then you can take a new piece of O ring wire and re-install it. Use a rubber mallet to GENTLY tap it back down into the receiver grove. Make sure you trim the wire ends at an angle so the meet up and look as though it's one continuious piece of wire. When you torque the heads back down it will seat like new.

o-ring
What position did you install the factory gasket?

I installed the headgaskets right side up...no problems there! Hey Cal, another thing you forgot to mention was to install the correct nuts in their proper place on the girdle
I was told that my machine shop did a fopa with the girdle, I made a call to them right after the new owner informed me of this. So what do you guesstimate this new motor to lay down at the tires??? Right before I sold it, it made 523 HP and 619 lb-ft on a Dynojet chassis dyno.

gaskets
Lets see if I got this right.
Turbo Joe, you used an o-ringed block, factory head gasket, installed right side up. No reciever groove.
Qwknuf6, you have the same setup but with the gasket installed upside down.
Both work ok
Thanks to all who replyed

Lee: When I rebuilt Joe's motor, I installed the head gaskets right side up.
Joe: I will be dynoing the car tomorrow (along with Champion's car). I doubt it will make that much hp since I am using a Mustang dyno that spits out lower numbers than the Dynojet. I wasn't going to mention the girdle stuff, we all make mistakes It certainly didn't hurt anything.

Cal,
Go ahead and mention it, it wasn't my dumb mistake I called the engine builder and chewed on his ass for a while about that, he must have felt pretty stupid as I handed him a detailed set of instructions for the girdle and told him to follow them to the letter...he must have thought they were DESTRUCTIONS instead! What kind of state of tune will you dyno it at? My numbers were made with 25 psi, 3rd gear, TCC locked, and 24* of timing with 100% B33 fuel. That 218-218 cam made great HP over 6000 rpm....nice and flat as well. Good luck, make sure you send me some numbers when you get'em.
