I gonna take my car into the shop to have some work done on the engine (stuff I can't do myself) and I have a set of rocker arms bought for my old 94' LS that I never used. The ones in my engine have only aobut 49,000 miles one them, my question is, while they are in the engine should I have them replace the rocker arms too or is it just a waste of my time and money?
