    Both intake and exhaust are to be set Cold at .026 or Hot at .024.
    Or if you like it "by the book" .025-.027 cold! [^]

    The "J" is a 3/8" reach, Non-Avanti Studebakers use an "H" 7/16" Reach = H-14Y, which now crosses to a new "stock number" in the Champion line.

    "N8N" -Nate, posts here and has the crossovers to ["better" @ ] brands: Autolite, Bosch, NGK on his website.

    @= Warning: controversial Forum subject, personal "opinions" will be contradicted!
