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.
