I have the Comp XE262H cams sitting in my livingroom and have a couple of questions. My car has 133K miles on it. I did get a suggestion to replace the valve stem seals. I'm going to get new valve springs for the swap but what else would anyone suggest I do? I just want to maintain reliability...not really build up the engine other than cams right now. What should I look for when I pull the valve covers as far as problem areas?
