    All Budget Headers are NOT Created Equal!
    Hooker's Competition Series Headers come in your choice of finishes and are engineered to perform at a reasonable price! To let your engine really breathe, Hooker utilized 16 gauge (.049'' thick) steel tubing attached to long transition style collectors. Giving you a serious increase in flow over other brand headers without a loss in the backpressure most engines need to perform! After years of testing, Hooker has discovered that a machined 5/16'' header flange offers enough flex to hold the gasket tight to each exhaust port plus enough rigidity to keep everything properly tied together.

    Features
  • Mandrel-bent tuned-length tubing for smooth exhaust flow and power
  • Sturdy 16 gauge steel tubing
  • Perfect seal 5/16'' machined header flanges
  • Long transition collector for improved power over standard headers
  • Gaskets and bolts included (Reducers sold separately)
  • Available in five finishes to suit your needs (see listings below for product availability) -

    Black Painted (Part numbers do not have a suffix)

    Metallic Ceramic Coating (Part numbers have a -1 suffix)

    Stainless Steel (Part numbers have a -2 suffix)

    "Darksides" Black Ceramic Coating (Part numbers have a -3 suffix)

    Titanium Ceramic Coating (Part numbers have a -4 suffix)

  • 4901-1 - Hooker Headers Competition Headers Chevy/GM Car is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Fit great I have installed headers on just about every square body I've owned. This set of headers was probably the best fitting so far, the passengers side was no issues at all and the drivers side had a small clearance issue with the engine mount. I needed to remove 3/8" metal from the corner and the A/C pump mount bracket needed some trimming.

    Will these headers clear the crossmember on a 1976 firebird with a pontiac 400 engine?

    Asked by: 1572
    It will clear the crossmember, but may require spacer on the mounts for proper fit.

    Do these headdmers interfere with the oil filter on a 1976 firebird with a pontiac 400 engine. Can the oil filter be removed normally?

    Asked by: 1572
    This header may need a slight modification of the oil filter or a remote oil filter mount in order to fit properly.
