These typically have clearance issues with the crossmember and the exhaust pipe connecting to the headers. You would be better off with the clipster headers 9300108 for your pickup.

These are painted black with high temp paint. It will last for a short time but if you are after a long lasting coating you will need ceramic coating such as our AHC coated headers 9300101H.

For fit to your application some dimensions to check are as follows: From head surface to furthest point outward is 4” and from top of head flange to bottom of the collector is 10”. The collector flange sits approximately ½” from the block. You will need to measure your application to allow for clearance for the collector reducer and adjoining pipe to verify fit.

These are actually a rectangular shaped exhaust flange with rounded corners. These work on nearly all stock small block Chevy heads and many aftermarket heads. The exhaust port shape is not actually round on this header.

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.
