Does anyone know if GM produces a graphite head gasket for a 6.0L?

A while back, I bought some used TEA o-ringed heads that were 4-5 months old. I sent them to TEA to have them checked out and ported out further to 77cc. I told them about what the application was and that I had the 6.0 motor. They also sent me a set of GM graphite head gaskets. Accoding to TEA, only GM graphite gaskets can be used on the o-ringed head.

Well, I started ripping my motor apart yesterday. I got one side completely ready to take the new head and went to look at the head gaskets that were sent to me and noticed that they were for a 5.7L. I waited until this morning to call TEA and ask if these are the gaskets I should be using and they told me no, that I should get a 6.0L gasket. No big deal, I thought.

I call around and the only place that can get them to me by tomorrow was Scoggin-Dickey. The only catch is, they can't tell me if they are graphite or multi-layer steel (MLS). Even the dealership cannot tell me if they are graphite, or not. The ones I pulled off are MLS. I went ahead and ordered them, but I am almost positive that what I will get are MLS gaskets.

I called TEA after my difficulty getting the gaskets and nobody was there that could talk to me. I call back later and they are closed for inventory to leave a msg, but that they would get back to you today, according to the msg. Well, I left two messages and got no call.

So now I am stuck with not knowing what to do. The 5.7L gaskets are so very close in size it's tempting to just go ahead and use them. They don't appear to overhang the bore and according to my calipers the bore sizes for the gasket and block are the same.

So if anyone knows if GM makes a graphite head gasket for the 6.0 - please send me the part#. Or, if anyone has ever used 5.7 head gaskets on a 6.0 block, let me know.

 

I'm sure they'll chime in when they see this...TTT for ya....

It's part number 14096405

 

Thanks. I'll give it a shot.

 

Looks like a gasket problem to me, not TEA heads problem

You should be fine using the multilayer gaskets.

 

Even with o-ringed heads?

 

Ive always been told to go with the copper gaskets as my motor is oringed as well.

 

Do you have the groove to accept the o-ring? Or, like my heads, have the ring embedded into the head around the combustion chamber?

 

I have reciever grooves in the block which accept wire inserts.

 

BENKEY,

Now that it was mentioned, cooper head gaskets probably are the way to go. I checked with an engine builder that has built nitrous motors and O-rings the block and has receiver grooves cut around the combustion chambers on the heads and he always uses cooper gaskits as well. The orings indent the cooper slightly and the receiver grooves on the heads accept this indentation which causes a more stable seal around the combustion chambers.

BTW I know this is a little off subject BUT you can oring EITHER the block or the head and then put the receiver groove in the other surface. I guess in your case you have the receiver grooves cut into the block and the heads themselves have the orings. One reason people may choose to oring the block instead is that in a rebuild the need to resurface the heads come up much more often than the need to resurface the block. SO if the oring is on the BLOCK side then when you mill the head you simply have to cut the receiver groove a litttle deeper to compensate for the amount of material you mill off the head.

 

I do not have any receiver grooves in my block or heads. My o-rings are part of the head only and protrude. It is a metal wire that has been cut into the head around the chamber and sticks out a couple of thousandths. It will be pushing into the gasket, but there will not be a rcvr groove to push to on the block.

 

Sorry I misunderstood, didn't see this post earlier, but I checked for you and it won't make any difference, the cooper gaskets would work well here as well.

 

Do you know the part number you ordered? Is it 12569365

Thunder has this number listed as the MLS gasket: 12575392

GM Parts Direct lists this as 6l head gasket: 88894351 (not sure its graphite)

I'm looking for the graphite part number for you.

 

Thanks for the help.

The 88894351 P/N is the entire kit. Comes with bolts gaskets etc... and runs about $200.

Scoggin Dickey would not give me the part number of the ones I ordered. Against policy, I guess.

 

I pretty sure the 5.7 gaskets won't work as we had a customer install these on a 6.0 with our S2 heads and it sounded like it was desieling at a idle from the pistons hitting the gasket. You could use a copper gasket but the water sealing issues would drive you crazy. You may be able to use the Fel Pro, but I am not sure if it will work. The earlier 5.7's were the ones that used the graphite gaskets, so maybe the earlier 6.0's did also. The MLS will not work, they will leak water, as the wire is out of the head .010"-.012" and does not allow the head to sit against the gasket and block. You would have to mill the heads .030" to get the wire out, which would take the chambers back down to 72cc. I will call you when I get to the shop in an hour.

 

If it turns out that I cannot use these heads for my application, anyone interested in buying refer to here: For Sale thread I will not have them milled to their near original configuration.

 

Problem solved, Fel Pro makes a replacement graphite gasket for the 6.0 and the best part is that it can be bought at Autozone, Advance Auto parts, etc.

 

now thats customer care.

 

Just to close out the thread with final comments.

I got the graphite gaskets for the 6.0L by Fel-pro. The part# is 9199PT.

Brian, of TEA, called me at home and talked to me. He was very sympathetic with the situation and was willing to do whatever it took to take care of me and make the situation right, which to me speaks volumes to their committment to customer satisfaction, for what he was willing to do. Somewhere during the conversation, he remembered that he had someone that had just gotten 6.0L graphite gaskets from Fel-pro a while back, originally, it was thought that Fel-pro didn't make them. So he steered me down that course and I found some. I had to drive around 130 miles round trip, but they are graphite factory replacement gaskets. The main problem with parts stores is, when they show the item on their computer or catalog, it does not tell them the specifics on what type of material they are made of. So, you have to sit and wait. Like the MLS gaskets that I paid to have overnighted to me from Scoggin-Dickey. A $40 gasket set that turned into about $70.

So, I am very happy now! Thanks, Brian. You now have a customer that is committed to TEA

Anyone looking for a set of GM p/n 12575392 MLS head gaskets for 6.0L - $35 plus shipping and they are yours. PM me.
