[LS1] ls1 timing chain options for upgrade

[Turtl3]

Hi all, hoping someone can answer my question. Ive got the front of my engine apart to do the oil pump and noticed theres a fair bit of slack in the chain. Could i use a rollmaster single row chain with the factory crank sprocket and cam gear or does the rollmaster chain have a different roll pitch?

What other options do i have for a single row upgrade (chain only), maintaining the factory sprocket and gear? Could i use a ls2/ls7/l98 chain?

I have read the ls2 chain is a good upgrade.

mmm yes...after doing lots of reading on numerous ls1 power-plant based forums, the stronger ls2 timing chain superseded the ls1 timing chain many moons ago. so when when buying OEM/GM the part number for early ls1's would have been 12586482, and now the part number that should be currently listed and supplied for ls1's, which supersedes the old number is 12646386 (ls2's). im going to give amcap a call first thing on monday and see if they can confirm this. if shes apples i will be getting one.

hopefully holden use the same part numbers that they do over in the US.
