Rocker Arms and Bridges
Hey guys thanks to the help of some and especially oldscutlass we have been able to determinethat I need to replace 2 rockers and a bridge. I have checked the bottom of the lifters and there Is no wear I went ahead and replaced all of them anyway. They are all primed and pumping well. My question is if I'm going to replace two rockers and a bridge should j just go ahead and replace all the driverside rockers and bridges? And if so does anyone know of a good kit with all that I need to so that. Lemme know thanks guys and gals!
Hopefully Wishfully With A 55gallon drum of luck the noise will go away haha.

It's a tough call, it's not necessary to change them all, however others may start to go over time. I posted a some parts and sent you a pm for those parts. Napa also sells them maybe a different brand but they are still available.

On a small block chevy engine with an adjustable valve train, the written procedure I have always read is to tighten the rocker pivot down to first contact then 3/4 turn more. I have found that 1/4 turn seems to work best although I am by no means an expert! Since the Olds engine uses similar lifters you can tighten the rocker pivots slowly and if they contact the pushrods and valve stems around 1/4 turn of being tightened they are probably Ok. If less, they are either worn or need longer pushrods. Since you have replaced the head gaskets they should all be very close to the same. The extra .020 inch taller gaskets will increase the head height in relation to the camshaft. Worn rockers, pivots, and lifters can all add up to not enough contact between lifters and rockers. If they are all too loose a new set of pushrods is probably needed. If it is only one or two, you can try swapping a pivot to see if that will fix it. If it does, that means you would only need a new pivot and rocker set. Lots of checking is the only way to know for sure. Just make sure you put all the rockers, pushrods, and pivots back to where they came from to keep the wear patterns together on the parts.

Here you go babafats..... the whole kit. Toss them in and torque the bolts to 25 lb ft.

Start fresh with decent stuff, and go enjoy the car. These newer ones are steel and not pot metal. Much better product.

Dude I'm so bummed out as I'm tightening down the bolt for the rocker with the torque wrench the torque wrench malfunctioned and snapped the bolt in half so now my protect just got 5x as hard and is gonna be really hard to find a replacement bolt the wrench worked fine for all the other bolts but for some reason this one kept tightening down with no response from the wrench.

I have literally 100's of extras
If you can't buy a grade 8 flange bolt at your local fastenal store or whatnot just shoot me postage a bit for gas and paypal and I will mail you care pkg. Could go out as early as Monday. You could also use a farm store/ hardware store grade 8 the right length w/o the flange.

That sucks, Eric. Sorry to hear it.
As for the busted rocker bolt, it should be no problem to remove with an extractor, and maybe even with a centerpunch and a hammer. It's not likely to be tight in the hole. Once you get it moving, it should just unscrew.
