My WS6 has about 70,000 miles on it and I have to change the head gaskets so since I will have it all torn apart I was wondering if I should replace it as well.

 

For 15 bucks you can get the upgraded LS2 chain. It fits over the stock sprockets. I'd change it

 

I'd change it as well.

 

I'm not a big fan of slapping a new chain in there and calling it done. I know a lot of people do it but it doesn't seem like the best way to go.

As an extreme example. If you ever owned a bike and placed a new drive chain on old, worn sprockets, you know what I mean. You'll go for a ride with your new chain, and after the first ride you'll have to take up more slack on the chain. That's because the worn sprockets have, almost instantly, stretched the new chain. I believe the timing chain and sprockets should be replaced as a set. JM2C.

 

I'd wait until you cam it to change the timing chain. JMO

 

change cam and crank sprokets along with LS2 chain, did mine too at 75K. Really cheap insurance. If you have some more funds change out intake manifold gaskets for like 60 bucks

 

I paid $24 for new intake gaskets this year..$60 is way too high..shop around..I got mine from Speed Inc...I have a set on the car right now that have been on two different intakes and they are fine..their life span is very long from what I have seen..they are 6 years old..
