D-PORT, Silver, 1-1/2 in Mid-Length, Engine Swap Headers For SB Chevy in 2WD S10

Standard-Duty, HTC Polished Silver Ceramic-Coated, Mid-Length Engine Swap Headers For SB Chevy (with D-PORT Heads) into 1982-04 2WD Chevy/GMC S10/Blazer Family; 1-1/2 in. Tube Diameter; 2-1/2 in. Ball/Socket Style Collector


Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing Chevy S10, GMC S15, V8 engine swap specific headers for over 30 years. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

These polished-silver ceramic-coated, MID-LENGTH TUBE headers are designed specifically for use on on a Small Block Chevy 283-400 (Gen 1) fitted with D-PORT heads (GM's ZZ heads have D-shaped ports) into 1982-2004 Chevy S10/Blazer, GMC S15/Jimmy 2WD trucks. Fits both manual and automatic transmission trucks. The smooth 1-1/2 in. tube design provides ample exhaust flow to let your transplanted 283-400 SB Chevy engine with D-Port Heads breathe easy, and produce additional horsepower and torque over factory manifolds.

To ensure a proper installation, it is recommended that these headers be installed with Trans-Dapt Performance Product's #9906 engine swap mount kit.

These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.

Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. These headers have a high temperature, POLISHED-SILVER ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5 year factory warranty, in addition to Hedman's standard lifetime header warranty.
