    Picked up some new header gaskets for my 72. They were square. But, the header and the block are oval. So, went back to Jegs, they did not have any oval shaped gaskets. Only round and squares. Can't find any ovals locally. What can I do?
    The headers are Dynomax ceramic and the motor is stock, Goodwrench.

    Back when I had dynomaxs i got a Fel-Pro gasket that worked fine. Have no clue what the part number was. Try calling Dynomax... they should have a list of part numbers for various manufacture s that work w/ the header

    Is the port on the block more of a D shape with the radius toward the top? If so than it is a "D" port head and you won't find headers that match up to it for a truck. I got a set of 1-5/8" primaries which cover the port completely and gaskets to match. The gasket will cover the prt in some areas, but you can set teh gaskets on the head and open them up to the port size if you want to.

    "Call Dynomax"....., why didn't I think of that.
    The ports on the block are oval. I wish they were D shaped b/c I remember seeing those at Jegs.
    Thanks fellas.

    How about a regular exhaust gasket from chevy or napa. Any major disadvantage?
