What's in the Box

Info

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 1950s and 1960s 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

Item Details

Header Dimension Chart

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.

Nice look, but no fit

January 26, 2016
These would not work on my 350 with straight plugs. There was absolutely no room for the spark plug boot on the middle two spark plugs on each side. Yes I was using the the shorty header plugs. Nothing would work. I asked all these questions before ordereing and was assured they would work, they did not. Speedway was great about returning them though. In my opinion, if you have a SBC with straight plugs do not order these headers.
No, I would not recommend this product.

Once product was exchanged for two match

July 26, 2014
Whoever is packing these items might want to look at them to see if they meets your advertised claim, before they ship. The exchange was handled very satisfactorily and new product sent out also did not match,but with both sets I was able to get a good looking set, they do look excellent and seem to hold up well once heated. Thanks for the Quick response.
Yes, I recommend this product.

The plating on the headers is not great

July 29, 2013
I bought a set of these to put on a Blueprint 383, they looked good at first, I cleaned properly before running engine, when I ran engine there was a large air leak in the collector, and 2 days later they started to surface rust. When I called tech/customer support they told me I voided the warranty on the coating and welds because they are not to be used on an engine that hasn't been broken in... but when I called tech support and told them about the application they would be used on they sure as heck sold them to me!
No, I would not recommend this product.

Merchant Response:

Toadwalk, thank you for your feedback. Your comments have been forwarded to Speedway Quality Control team to ensure current inventory of these headers meet the intended requirements. Unfortunately, these headers were purchased in August 2011, and therefore; Speedway is not able to warranty exhaust products after 2 years from purchase. We apologize for the inconvenience along with possible defects that may occur with our products. Speedway Motors thanks those that bring these issues to our attention to ensure that our customers have the best experience with us in any way.

Great attention to form/function/detail

March 02, 2012
I use block hugging headers for their compact design. This frees up space in my engine compartment for easier maintenance and cleaning. The fit and finish quality of these headers far exceeded my previous ones and cost 1/3 less.
Pros:
  • Includes great gasket
  • Access to all fasteners
  • Installation is a breeze
Yes, I recommend this product.

Our tight fit headers have the furthest out point at the bend in the tubes which is 4” and from the top of the flange to the bottom of the collector is 10”. The tubes wrap inward and are within 1” of the block at the collector flange which is directly below the center two cylinders. You can compare this with your frame to verify clearance.

In some cases over tightening actually distorts the collector flange so check with a straight edge and correct if needed. If still leaking your local parts store should carry exhaust gasket or exhaust sealant. It normally comes in a tube and applied to both sides of the gasket. As it sets up it helps take care of irregularities. Some suppliers recommend only one side to ease removal down the road.

They stick out further from the block, than the ram horns do. But I am not aware of any that will be that tight to block. Ram horns will definitely not breath as good as these headers.
January 02, 2013
Jason
These tight fit headers may NOT fit all applications where ram horn manifolds were used. There were many different rams horn manifolds offered by GM with different outlet locations. From the head surface outward the tubes furthest point is 4” and from the top of the flange at the center two ports the collector is 10” down. On applications where the cross member is directly below the center ports it may be difficult to hook up the rest of the exhaust by the location of the collector.
