Just a quick question on LS1 block: I'm getting ready to put my cylinder heads on. So, do I need to apply any "thread sealer" at all on any of the head studs (obviously on the block side)...????

I used arp moly lube on my studs, some peple will use locktite when threading them into the block.

My main concern is if there are any threaded holes on the engine block that actually goes thru any water jackets that would require any thread sealer.

Thread sealer is not needed, just moly lube that arp supplies. Hand screw them into the block till they bottom out, which make take a little bit of effort depending on the condition of your block threads, but after bottoming out, back them out an eigth to quarter turn.
