These Black-Maxx coated, MID-LENGTH tube headers fit 1967-74 4WD Blazers, 1/2 ton and 3/4 ton Chevy and GMC trucks, Suburbans with a SB Chevy engine (check the application listings for exact fitment). The smooth 1-5/8 in tube design provides ample exhaust flow to let your Blazer or C10/C20, C15/C25 truck's 283-400 SB Chevy engine breathe easy, and produce maximum horsepower and torque. The MID-LENGTH design of these headers keeps the header connection up, tighter to the body, so you can keep your entire exhaust above the frame rails.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.
