double roller timing chain

Regarding the double roller, here is some info from a reputable source (Joseph Potak's LS book):
LS2 timing chain is stronger than LS1
double rollers are about 50% stronger than single roller
the factors that impact the need for a double roller are: high rpm's, high valve spring loads, and agressive cam lobes.
A nice feature of any aftermarket chain kit is the ability to adjust the timing by re-adjusting the crank gear on the keyway.
I chose a new LS2 chain/gear for my build because I will not spin past 6k, my valve lift is .570, and my cam lobes are mild XE. Assuming my timing events check out ok, I wont need to upgrade to an adjustable setup.
Hope this helps.

Often overlooked but likely more important. The timing chain damper will help prevent chain wrap and breakage. These are hard to find though. Most important, harmonic damper (pulley) will also play a major role in timing chain life. Some aftermarket harmonic dampers have been linked to timing chain breakage.
