    Default stock heads + boost

    I just wanted to see how much are the hp limits of stock unported heads.
    I' ve have had my build stopped because i cant afford good flowing heads "2,000"
    My plans are turbo 383 street/strip 600-700hp.I already have an all forged eagle
    rotating assemble and almosts done bottomend.Or maybe someone can point me to
    a good cheap plce to get my heads ported

    untouched stock heads will really hurt you, but Lloyd Elliott and Advanced inductions both do great work with heads for good prices.

    LE can port your heads for under two grand, easily. But even ported those heads will choke the 383 down at higher RPM's. You'll find your HP limitation in the heads.

    So many turbo builds going on lol.

    I went with LE stuff. He's a great dude, awesome support, and amazing work. I wouldn't trust anyone else with porting.

    Im thinking the le2 heads are in my budget.Now I need to figure out if the cr is going to be
    low enough.I have -31 dished and stock deck height.Im going to see if i can figure it.
    Im looking to get 9.5-1 or alittle less.Thanks for the direction.
