I pulled my rockers, push rods, and lifters. I will be getting my new restricted push rods from Smith Bros. and my cam and lifters from Claysmith on wed or thurs next week. My question is this I was reading thru a Hanes manual I have on the Olds 455 and it said to keep the lifters, rockers and pushrods in order. It is my understanding that you only need to keep the lifters in order because they are worn in to the specific lobe at that specific position. Is it necessary to keep the other stuff in order? Also when I put the new cam in does everyone else use assembly lube when putting it in, and yes I am going to degree the cam.
I use GM E.O.S. (engine oil supplement from any GM dealer) on the cam lobes.
You should keep the rockers on the same side of the same stands they came off of due to matching wear patterns, and if you aren't doing anything to the valve stem tips you should keep the rockers on the valves they came off of, same reason.
well I put them all in a bag, Does that mean I need to buy new ones? and if so why?
Just how big a cam are you going to run? You may run into problems trying to use the old valvetrain with a lift over .500" weather you kept them all in order or not.
I ordered it thru cp performance. I told them I do not want anything that is performance, they said it will be mild and Just for what I have. My biggest question is on the rocker arms I thew them all in a bag, damn. Well live, learn and spend more money. Do I need to change the rocker and the bridge or just the rocker?
If you put them into a bag then thrash them. If your going to install a new cam them you need new lifters(extra insurance). It doesnt matter where you put them if they are new. You also need to do a cam breakin again to avoid flattened lobes.Trust me I just did this wink I am also going to agree with king. Add the Gm E.O.S! That stuff is the best(any gm dealer has it)! Use it with lots of cam lube! You can never be too sure. Also make sure you prime the oil pump first and you are ready. Good luck and let us know the results wink wink

would I replace the rocker arms only or the rocker and the bridge that connect the rockers to include the bolts.
I always look at the part of the bridge that the rocker arm rubs on. Look for the wear lines, if they are more than just visable they will hang up with a cam of different lift. You could try maybe hitting them with some 320 grit and lube them up good with assembly lube, but they should probably be replaced.
I assume I can get them from an autoparts place, any idea on how much a set goes for?
They are dirt cheap. Autozone sells them for (i think) $2.99 each or something like that. The bridges are like $4.99 each. Go to www.autozone.com and search for them. Look them up under a 76 olds w/ 455. All of our prices and parts are on line!
