The springs are the weakest link. Before you start worrying about rod bolts, you have to change your springs. While you're changing them, you might as well change out the pushrods. After that, you'll want to think about rod bolts, and getting the ARP rod bolts should make 6800-7000RPM relatively safe.
I'd also recommend upgrading the timing chain. The LS2 timing chain is a common choice due to its low cost and the fact that it'll use the LS1 timing gears.
