    l92 heads anyone?

    has anyone heard of these? they're reported to flow 330cfm on the intake side. for 375 bucks each head, assembled, it sounds like a hell of a deal. they're avalible through GMPP, PN 2582713. then theres the matching intake, also through GMPP, PN 12580123 which also comes with 36cc injectors, fuel rails, and a 90MM tb, all for 475 bucks.

    has anyone heard anything else about these? apperently the parts come off of the 6.0 tahoes with the l76.

    all of this info was sourced through hot rod magaizne, so ill assume its correct.

    its just a guess, but i would assume these are unported ls7 heads.

    l92 are the ls7 heads and i dont think they'll work on a stock 346. I havent done much research on them for that fact right there. The bore sizes are different.

    they actually have a huge thread going on ls1 tech. i guess they will work with ls2's or larger.

    right, the ls2 is a 6.0 liter with a 4.00 bore. the l92 heads are too big for the 3.898 bore...something like that.
