Default LS9 Head Gasket?

I am trying to find the Part Number for a set of LS9 Head Gaskets so I can Install my L92 Heads to my Stock 6.L LS2 Block...I was using the stock GM MLS Head Gasket 4.60" and when tuning the engine to run on e-85 fuel I blew one or both of the stock head gaskets, one or both heads must of lifted.

The stock heads are ported, so is the Intake, I am using ARP bolts, in other words i have all the good stuff in the engine.

I tried doing a search but there is so much gibberish that i can't get the info i need.

Can some one please chime in and help me get back on the road...

Regards,
crakhead

Would you happen to know what the Bore is on that part number?
Or the thickness?

Thanks for the Heads up 5 Liter Eater...

They are the same thickness as the stock GM-MLS...when i tune it back to e-85 and start giving the engine more timing i hope these suckers are going to take the abuse and not lift the Heads, mind you my car is N/A...

Has any body tried any other Gaskets, like Fel-Pro, Cometic, Athena, cause I know they come in different thickness and Bore sizes...

PS: I just got my gaskets along with a bunch of other stuff from Summit. The bag they came in was labeled with the correct part number but the gaskets were not LS9 gaskets. They were incorrectly packaged. So check the part number on the gaskets themselves when you get them from whereever you decide to get them from.
