    Manufacturer's Part Number:
    Rated 5 out of 5 by from Great for aluminum heads I bought these for use on a 4.125" bore SBC. This particular gasket was designed for the 400 SBC with the steam holes, but will work on any SBC where a large bore gasket is needed. These gaskets seal very well, do not need retorqing, and will not brinnel aluminum heads. Can't ask for much more.
