    SBC Head gasket question

     



    I am building a SBC with Edelbrock aluminum heads and intake.

    I noticed the head gasket between the 3/5 and 4/6 cylinders has small (1/8") holes, but the block and heads water channels have much larger holes (1").

    Can I drill out the head gasket to match the heads/block? I never drive my car in the winter so I would like to keep it as cool as possible.

    You are not by chance talking about the "steam holes" in a 400 SBC head gasket.

    Yes, they are the small holes that line up with the water channels on a SBC (I have a photo on my "See Photos")

    those holes should stay like that, they're supposed to slow the water down to allow more heat transfer before getting back to the radiator
