    11530 is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Fitment 83 c30 454 4x4 4 spd, bolt right up without modification. Driver side was a little tight going in but fell into place once they were in. Still have big oem starter, cleared just fine. No issues with clutch. Passenger side collector dumps pretty well right into the crossmember so the bend was difficult but do able. Hope they last a while.

    Rated 4 out of 5 by from I bought these to install on my 66 C10 that I swapped a Gen V 454 into. They installed with no problem at all, My only complaint I really have is passenger side collector is aimed slightly down so with my purple hornies installed, I might have to heat it up and try to bend it up. But I have had that same problem with the hooker headers I installed in my 81 K10.

    Will these fit in a 79 k20 I swapped in a 454 with standard transmission manual clutch?

    This would be the correct header for your truck.
