Yes, However they are reconditioned ones for $25 a piece as listed in their catalog (pg 56). If you can swing it, might I suggest a set of Toms adjustable rockers. This would be a nice upgrade both in adjustability, and performance. The performance here will be mostly due to the improvement in the rocker ratio. The stock rockers have a ratio 1.40 to 1 wherin you will be 1.60 to 1 with Toms of other aftermarket ones that are out there. That is... since you are replacing them anyway...:TU: Erik
For Adrian's purposes, there's no point in spending that kinda dough on Tom's rockers, especially when he only needs a few replacements.
...hence the "If you can swing it" part... That's certainly and option to replace just a few of them. Maybe it's just me, but I was assuming he was talking about replacing all of them as a set anyway. I guess I'm an "opportunist" when it comes to ugrades. Oh... and btw... Gessler now has "new" factory ones for the same price... Erik
Just to clarify things, I just discovered that nailhead cylinder numbers are actually opposite, so the problem pushrods were actually on 2 and 6
If rockers are worn & needed I GUARANTEE the shafts are N/G also. I have actually just replaced shafts only with worn rockers in the past & the noises disappeared. I have many good used rockers, used pushrods & new shafts. I don't like using a hammer to remove the stands. Usually what happens, without your knowledge, is that the stand starts to get "Cocked" & if you hit it hard enough with the hammer more than likely it will break!! As well as marking up the stands!! I remove the end rockers & using the rocker arm that is next to the stand, I stand the shaft on the bench & pull down on the rocker against the spring & use it as a "Slap" hammer. If the rocker doesn't slide easily use some carb. cleaner to clean the shaft until the rocker will slide. Now pull the rocker against the spring & let it snap up. You may want to use gloves because after awhile your fingers will get sore. Keep pulling the rocker down & let it "Slap" against the stand until the stand starts to move & comes off. You now have 3 stands left. Do the same to 2. The last stand will have no spring or rocker. Put the shaft in a vise so the shaft is loose. Now take a plastic, hard rubber, lead or brass hammer & hit the end of the shaft & a socket or other similar tool to get the shaft totally free from the stand. The stand will come off easily. The secret here is to keep the stand square to the shaft so it will not start to come off un-square. I have been told by some that they break the stands installing them on new shafts or material is being removed upon installation. Even by some more accomplished. Easy remedy. Heat the stands in the oven to 400*. Remember to use gloves. I had to say this as I was told one time that "I burned the s*&%X out of my fingers" because you didn't tell me this. They will now slide right on. Or, another option just send them to me & I will do what's nec.
Torque specs for the 4 bolts that hold the rocker assembly down, intake manifold, and valley pan? I don't have my chassis manual yet...uzzled:
Would it be "rocker arm bracket to cylinder head" in this list? http://www.v8buick.com/attachment.php?attachmentid=4608&d=1047989466
Yes thats it. 25-35ft lbs. As you tighten take it slow and tighten each one a little in sequence to bring the shaft down fairly even. As you tighten you will be compressing valve springs. Make sure the 2 dowel pins are properly aligned with the holes in the shaft stands as you are tightening and the push rods all stay in place. Use assembly lube while putting the rocker shafts together as well as a dab on the ends of push rods and valve stems. The intake torque is 25-35ft lbs. Specs are with threads lightly lubricated.
I'm hoping theres not something wrong.... I got the new rocker arms and pushrods today, installed em and it was relatively easy, went to put the whole assembly back on and tightened it all down, but I then notice that one of the springs is more compressed than all of the other ones, so I took off the other side and they were all an even height. Is something wrong. Heres a pic

Whew! I was concerened because on the otherside they are all even and this is the only one on this side that is down. Good stuff. Thank you!
Based on that question I would say that not only are you doing darn well for what you know, but you have guts to take it on. Not that it's something that you can't do with a little help but it takes some guts to dive on in. You will be so much smarter about engines and so glad that you did it when you are done.
To tell you the truth when i began i was terrified of just taking off a manifold. Now it was the rocker arms...no longer. Its a big confidence builder, and I actually feel good about it
How in the H#$L do you keep the Oil from running out all over the place with the engine upside down with the valve covers removed. Sorry, I couldn't resist
