you can keep your gears and just use the ls2 chain. the ls2 chain is heavy duty.

LS2 chain is beefier than LS1. You could run the chain using your LS1 timing gears, just the chain.

Just go with the LS2 chain, its stronger than the factory ls1 chain for $35-40

i guess I have a mis understanding of what you guys are talking about. Take a look at this link:

The bottom two are ls2, and the bottom one is ls1. Which should i go with? or is there something else in the market everyone else is using?

Most posters here assumed you were talking about the stock OEM chains. The stock OEM LS2 timing chain is much stronger with beefier side plates. I run this chain along with the timing chain dampner with zero problems. If you want to run an aftermarket chain, then run the LS1 version shown in your link. Hope this helps.
