Brand New Pair of Southwest Speed Ceramic Hot Coated Long Tube Headers for 1963-1982 Corvette's with Small Block Chevy 262-400ci Engines (Part #440-2234). This Pair of Southwest Speed Small Block Chevy Long Tube Headers offer an immediate increase in performance by eliminating backpressure, improving exhaust flow, and building more horsepower. Constructed from cold-rolled, flash-controlled 16-gauge steel tubing and finished with a black satin paint or silver ceramic heat resistant coating these headers are equipped with an O-ring port seal and 5/16" flanges that are heavy enough to maintain complete integrity, yet pliable enough to create a leak free seal. The consistent tubing diameter contributes to the smooth air flow and greater exhaust velocity of these carefully engineered headers while the precision welded collectors give you a perfect fit. Headers do not have an internal coating. Applications: 1963-1982 Chevrolet Corvette Notes: Must modify stock exhaust to retain catalytic converters. Will not fit with A.I.R. pump. Installation on vehicles 1978 and earlier with air conditioning will require purchase of 410-5815 bracket. 1979 and later vehicles equipped with short compressor will re-use the original bracket.
