I had a set of Patriot LS6 heads put on mine and needed to swap the ls1 head gaskets for a set of 6.0L head gaskets (went with the GM LS6 truck gaskets as they were the only one's available at the time).
The LS2 head bolts are different then the LS1. Where the LS1 has long and short head bolts. The LS2 only has long bolts.
Valve covers were centerline on most of the LS1's. I think 97 vette and 98 fbodies were the only ones that aren't centerline for the bolts.
Hmmm...can't think of anything else to change out.
Doh I'm probably missing something though...

so would i need ls1 head bolts for the ls2 heads, i saw someone selling "ls6" head bolts for bolting the ls6 heads to an ls1 on ebay. would those be similar to the bolts i would need? and i would use a regular ls2 head gasket right? made for the motor.

ARP part number 134-3609 says it will fit the 6.0 "gen III/IIV" "head style-LS1" what is this supposed to mean? and the ARP part number 134-3610 says that it is for heads with all the same length bolts.

lol nobody knows what head bolts i need? i need to know this info ASAP so if anyone knows please chime in. and if ill have any other problems! i am trying to get one last race in before the end of this month when the track will probably close.
You need to know what year your LS2 is , Because all LS1 & LS6 & early LS2's used the same head bolt ,long bolt except the out head bolts they were shorter , now on the newer LS2 i beleave late 04 early 05 they went with all long bolts .

The heads don't have nothing to do with it ,its the depth of the threaded holes in the block, the only difference in the 98 and 99+ is the valve cover bolt pattern. I also have the 05 LS2 with Dart casted heads. You haft to use the new style head bolts

yall are wrong about the head bolts, the ls2 uses all SHORT head bolts, not long, as far as the rest of it you sound like your all set. you will need a new vally cover tho, you have to use the ls2 vally cover. I just did this swap myself. Awsome power!!
