    PRC LS6 CNC Ported heads?

    texas speed offers these heads and claims that with their competition valve job u should see around a 50 rwhp gain. i was lookin at buying these heads and a cam for my first major upgrade. anybody else have these heads or similar? will i see gains close to this? for just over a grand they seem like a good deal.

    I already had a 238/242 .605/.610 110+2 cam and dynoed locked stall 390.2rwhp and I put these heads on with GM MLS gasket and gained 31rwhp and 19rwtq and that is still just the tune for the cam only so there might be a few more ponys in there waiting to get out.
    This is in a 2000 TA A4 3800 Vig stall and Moser 12 bolt with 3.73's also car has all bolt on's

    50 rwhp is on the high end of h.p gains. expect more so around 35 rwhp

    I installed their stage 1 prc ls6 heads off the shelf $899.00 jobies along with a torquer v2 and a Fast...i picked up 49rwhp over my old cam with stock heads...went from 393 to 442..but i am a M6 also...but realistically without a Fast you'll see about 35rwhp. they are pretty good for the money regardless.
