you can do roller rockers. that will help. but I use the stock ones even on my 408 and have no issues. besides sounding like a sewing machine. haha. I have also seen ls1's run 150k and 200k before a rebuild. I dont think that is necessary unless you beat on your car a lot. heck I have 120k on mine the 408 is new and the exhaust system but everything else is stock.
