    gasket kit question

    i am dropping a cam in the silvy and swapping heads at the same time. and need to know if the ls1 gasket kit on SDPC will work on my truck. it comes with everything i need and isn't too expensive. but will the head gaskets be wrong because of the different bore?

    If I remember correctly the 5.7 gaskets actually are stamped saying 5.3 and 5.7L.

    Double check the PN on the head gasket first.

    considering they sell one gasket to cover the 6.0, 5.3 and 4.8 I would think that the 5.7 gasket should work just fine since they all fit the same heads and blocks. The LS1 gaskets are cheaper for some reason.
