    You may be able to get a nut splitter in there. Use it to split the nuts then chase the threads after you get it apart and use the anti-sieze when you put it together. It can save a lot of time not messing with the old nuts.

    Thats what I am working with. The angles to get a socket in there absolutely suck. I had also never seen that middle "donut" (for lack of a better time) on a car before. The gaskets that I was told to purchase via NAPA's website look like a blue graphite donut instead of a flat gasket. Is this the correct gasket?

    I hope those dorman studs are a dollar each and not $100, but i haven't priced any in a while and nothing shocks me anymore!

    Well!!!! actually I was suggesting that he take the car to BP (Bob Palma) and have him spray his PB Blaster on the parts.

    In any case, Gary Thanks for cleaning up my oversight.

    Remember too, cast iron can take a lot of heat. Torch it cherry red with an oxyacetylene. Quick shot of Blaster. Don't give it a chance to cool before wrenching with a six-point socket. Remember afterwards, your socket will also be very hot.

    In the worst case scenario: i.e. the exhaust studs breaking off the 'ears' from the manifolds: new ones are available from Dorman and a few other outfits for about $100 each. Just specify a Ram's Horn for a 1960's SBC.

    As crazy as it sounds that heat it up and put a candle to it works great. I've done it many times myself on frozen bolts. Not %100 but has gotten me out of more than one spot.

I have the gaskets ready to go, just need to pull the thing apart to do it. No air tools to work with. Anyone got a tip or trick breaking them free?


    Got a couple other shops to try, hopefully they will work on the rusty ones.
    My mechanic son's trick on frozen bolts/nuts is to heat them with a propane torch then rub an ordinary candle on the heated part then put the wrench to them (six point as another suggested). On reassembly anti-seize is your friend.

    I actually read it as PB Blaster. I will spray that on there tonight.

    I have to drive it tomorrow. So I will suffer with the leak for another day. If I can't get it taken apart this weekend, I may take it in to a shop next week that I have gone to many times before to see what they think. My old Dodge came apart so easily when I needed to fix the exhaust, its kind of frustrating that the Stude is being so stubborn! lol

    IN order to remove the manifolds, you may have to cut the pipes a foot or so down from the flange. If the metal in the pipes is good, you can weld them back together later.

    You may be better off to remove the exhaust manifold on each side, so you can get at it better, since you may wind up doing some drilling and tapping. While you are at it, have the manifolds "surfaced" at a machine shop. Put it back with all new fasteners, and use "anti-seize".

    Everything Bob said and use 6 point sockets ,wrenches if possible. Good luck.

Hit them with BP Blaster from above and also soak the studs and nuts with it. After a while, heat the studs with a torch and spray again. Keep this up on both the nuts, hole and studs. Remember acetone is flammable so I'd try the commercial first.

    Also use a wire brush to get rid of as much rust as you can.

    What you are trying to do if wick the release agent into the threads. Hopefully this will help. If you don't have a torch use a propane torch.
