    Spark plug for BBC Square Port Heads?

     



    Engine: Gen VI 454 Magnum

    Local speed shop set me up with NGK BR6FS plugs.

    Does that sound right?

    I gapped them at .40 thousands for use with MSD 7AL

    They're going in kind of hard? Maybe due to some spray paint on threads on head when engine was painted?
