Unless I get some differing advice that seems good I think I'm going to order parts tonight.

I'm thinking that Summit kit which has better springs than the factory made by PAC and the same trunion kit that Tooley sells (which is out of stock right now) and add the lightweight Tool Steel retainers. Plus the Magnum 5/16 pushrods.

I'm thinking the replacement of the springs and retainers are excessive but since I'm in there it'll be good piece of mind. I'm at 35K miles.

I'll probably do some plugs too while I have them out. Stock are the Delco iridium 41-110. I was told by my tuner to run TR6 plugs which are one range cooler than stock. From what I've been able to figure out the 41-104 (from the ZL1 and ZO6) is the equivalent heat wise to the TR6.

Any thoughts? That one rocker is rattling and I need to fix it this weekend.
