    Lookin for some headers for the 454 goin into my '83 K20. I've been lookin at the Thorley Tri-Y's. Does anyone here run a set with a big block? Hows the fit? Any installation problems? Any reason to get anything else of comapreable quality? No cheap ass $129 Headman or Flowtech junk. Getting closer and closer to swap time, Just tryin to get all the bases covered. :)

    I've got a set of Hooker's in my 72 that have worked real well for about 7 years. Not once have I replaced any gaskets, but it doesn't get a lot of miles.

    I'd trade my S&W .44 magnum for a D60 though.:D

    I am interested in this too. Going to swap heads and headers on the 502 and want good flowing and fitting headers.

    Been running the Hedman Elite series for about 4 years and haven't had any problems. Kinda close to passenger side shackle though.
