<p>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.</p><p>These polished-silver ceramic-coated, MID-LENGTH TUBE headers are uniquely designed to provide additional spark plug clearance when installed on a Small Block Chevy 283-400 (Gen 1) fitted with Angle Plug heads ( GM L98 aluminum heads, or equivalent design) 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 breathe easy, and produce additional horsepower and torque over factory manifolds.</p><p>To ensure a proper installation, it is recommended that these headers be installed with Trans-Dapt Performance Product's #9906 engine swap mount kit.</p><p> 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.</p>
