Holley/MSD is pleased to announce the release of RacingHeart Small Block Chevy Street Stock Long Tube Headers, which are a perfect fit for 1973-88 GM G-Body vehicles (Monte Carlos, Malibus, Regals, Cutlasses, and Grand Prixes) and 1970-81 GM F-bodies (Camaro and Firebirds). Available in two different finishes – natural stainless steel and black-painted mild steel – they come in three different sizes to accommodate numerous applications: 1-5/8 x 3”, 1-3/4” x 3” and 1-3/4” x 3-1/2”. They're compatible with both straight and angle-plug cylinder heads but must be used with a short oil filter. The header flanges are 3/8” thick for maximum strength and sealing, and the collectors feature merge spears for increased exhaust velocity.
