Q & A

What's in the Box

These AHC small-block Chevy tight fit headers are the most universal steel tube headers available. These performance headers fit difficult applications where space is limited. They are a favorite for street rods, as well as many 1950's and 1960's cars and vintage trucks. These ceramic coated headers provide superior performance and durability.

Tight Tuck headers are the solution to many problems associated with engine swaps in modern street rods. Tight Tucks fit in the tightest of engine compartments and clear all stock motor mounts. Most headers are manufactured from durable 16-gauge tubing and comes complete with gaskets, header bolts and collector reducers.

  • Most tight fit header applications require the use of Accel shorty spark plugs
  • Round port
  • Compact design
  • Will NOT fit angle plug heads
  • Includes reducers, gaskets and bolts
  • Armor Hot Coat finish

Application

  1. Can be used with most oil filter systems and transmission/starter combinations.
  2. Will not fit '55-'57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engine's center two exhaust ports.
  3. Will not clear a "clam shell" style motor mount (found on 1973-newer Chevy cars & trucks).

Warranties

AHC Warning: AHC coatings will burn and be damaged at exhaust temperatures over 1300 degrees. A lean fuel mixture can generate exhaust temperatures exceeding 1700-1900 degrees. If the coating is damaged due to a lean condition, the coating will not be warranted, but can be recoated for a fee.

Not legal for sale or use in California on pollution controlled vehicles.

Tight-Fit Stainless Steel Small Block Chevy Block Hugger Headers
(Part #9300107)
                        

The most universal shorty header just got better! Now made of durable stainless steel, these tight-fit headers feature a heavy duty 3/8" thick flange to minimize warpage with 1-5/8" diameter primary tubes and 2-1/2" diameter collectors. Block hugger headers are ideal for street rod engine swaps and can make tight installations easy. They tuck in close to the engine block to provide clearance for frame rails, steering boxes and motor mounts, but please see dimension chart to verify fit for your application.

The head flange features tall oval ports, so they will fit a variety of small block Chevy cylinder heads (EXCEPT angle plug heads). The collectors exit parallel with the oil pan rail to provide maximum ground clearance. Headers include gaskets, collector reducers with a 2" diameter outlet, and stainless steel installation hardware.

NOTE: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.

Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.
