rocker arms OK, so everyone is telling me that i need to replace the rockers on my LS1 because of the needle bearings in my oil pan... so i can get rockers and replace them just fine, but how do i know what to buy that will fit under my stock valve covers and will be a nice power adder for a descent price... i've already looked at yella terra, but i would like more opinions. i've looked at a couple GM Performance rockers and noticed some of them say "will not fit with stock valve cover" so how will know which rockers will fit when i am shopping online if it doesn't say one way or the other? is there a certain measurment i should be looking for?
realize that if you swap to higher ratio rockers...you also have to swap springs.
they are NOT a simple bolt on....not hard if you kknow what you're doing...and have the tools. but not easy either.
search around...one of the companies ( i think yella terra) offers "upgrades" to stock rockers. little more cost effective.
i'm not aware that any of the higher lift rockers interfere with the covers. although i did have to clearance a little for my HS 1.7s...mostly just excess casting along the inside edge of the head-valve cover gasket surface. nothing 5 mins with a hand file couldn't solve.

Check this out, used stockers with low miles on them. Seems like a good deal:
