    looks bad for my FE

     



    two almost dead cylinders, the two close to firewall, on opposing sides,

    I believe 4 and 8.

    spark plugs are white, (death white).

    Trying to figure out what may have caused this. no vacuum leaks, no pinging.

    new edelbrock 750, may be jetted too lean?

    low comoression on both, not smoking at al, runs strong, must have burnt
    valves.

    not a good time to be dumping more money into a "toy".

    Squirt some oil in those cylinders and recheck your compression. If it goes up, rings. If it doesn't change, probably heads (valves, gasket, etc.)

    Could be that your valves have tuliped, and are sitting off the seats. We've gone to SS valves across the board at work when doing a revalve job. A lean condition, high heat, and wrong timing can take valves out pretty fast.

    Pay close attention to the old head gaskets when you pull the heads. Stock steel gaskets will sometimes rust out the water blocker that stops the coolant from flowing through just the front of the engine. That causes the back cylinders to run hot, cooking the valves. If there are any holes corroded in the gaskets, better check the heads for cracks or warping. Putting the gaskets in backwards does the same thing, only much quicker! BTW, the back two are #'s 4 and 8, 1234 down one side, 5678 the other.
