It's a pain in the *** too so if not to save $300, at least you can save a weekend of wrenching. I swaped out to LS7 lifters and used the stock MLS gaskets #12498544 and ARP head bolts. The LS6 MLS head gaskets ended up being $26 for the pair from GMPartsDirect.com and as for the ARP head bolts, I don't know if they offer much advantage over the stock ones but they are $113.95 from Summit.

12617944 for most LS Based engines...
Here is what I found... Copy and pasted... I will update my list....
LS Exhaust / Header Gasket - sold as a single gasket, requires two pieces for one engine.
This is the factory replacement exhaust gasket for most V8 LS applications since 1997 -- fits LS1, LS2, LS3, L76, and L92 applications. Not designed to fit the stock exhaust manifolds for the 2001 thru 2004 LS1 or LS6 Corvette - these apllications use GM gasket part number 12576221.
The large round design of this gasket #12617944, will fit most aftermarket header applications and the GM stamped steel design provides excellent sealing capabilities for the most severe applications
