    Gap them at .35 if your forced induction or spraying, otherwise i would keep them around .55 or .60

    Which plug?

    Compression with those heads?
    Did you have to flycut the pistons to fit that cam?

    stock ac delco plug
    compression ratio is little higher than stock because of 5.3 heads
    no machining to fit camshaft
