    when changing exhaust manifold gaskets on a 512bb, can it be done w/ engine still in place?

    you have to remove the exhast to pull the engine, so I'd say yes to your question.

    Absolutely...as the engine cannot be removed from the car with the exhaust manifolds on (still attached to the engine). To replace either the 4-6 header gaskets, or the 7-9 header gaskets, the front headers on the corresponding side must be removed first to gain access.

    And, naturally, the mufflers and chassis cross-over brace must be removed first.

    Yes?? I think you meant no...Yes?

    Hi David,
    I meant "yes" to his question about "engine still in place".

    Off the main topic - I was able to pull the shift shaft out with the headers in place. Pretty cramped and no fun!

    BTW: That's your car. Georgeous!!!

    I pulled these about a month ago with the engine in place to replace the differential side cover gasket. I bought a set of 1/4" wobble extensions from Harbor Freight for around $12 that were a life saver. A conventional 3/8" U-joint extension will be too close to the header when on the 12mm nut.

    Not really that tough of a job but your hands will get banged up a little.
