Thanks moper and everyone else! They are all the same retainers. I thought about some different locks for the exhaust side. I may still look into it. I was just worried about coil bind, they are crane springs, and are good to well over .500, and my cam is only rated at .460 on the exhaust side, not taking into consideration I have stock rockers so I probably won't even see that. I've been meaning to ask about this for a while. Sorry jackel440 if I highjacked your thread, I thought this might be of interest to you too!
