these are GM cnc ported ls3's. who ports them for gm i'm not sure. i really don't think you can beat the price on them considering stock complete heads new sell for $725+ shipping. also i perfer a USPS postal money order. if you wnat to see some feedback on me go to ls1tech(94 guy) camaro5(94guy) or ebay (jjthekingkong).

this is all i can give you on the heads. i never flowed them. i've been told that they are cnc'ed by either texas speed or sunset racecraft. either one of those are good companies.

also these are ls3 821 casting with the stock hollow stem valves on the intake side. for the price i'm selling them for you could sell your heads and have about half the money in these. also how many miles are on your heads and what kind of condition are they in? i may be able to move them
