We dig GM G-Bodies around here. They are relatively light, have suspension that allows them to do anything, and you can stuff just about any combo into one. Unfortunately with increasing emissions regulations across the country, not everyone can slam a big blog or evil small block into one and still make it through their emissions testing. But thanks to Hedman, you can build a nice small block and keep it emissions legal. Whether your car came with the 305, 307, or 350, these headers are legal, and if you have the thought of building a stroker small block that will pass the visual and sniff test, these Hedmans could be the right header for you as well.
Full-length headers are the most effective, and most emissions legal headers are shorties or mid length which are NOT as effective. Check out these full-length headers from Hedman if you are looking for full-length legality.
LET YOUR GM G-BODY BREATHE EASY
Hedman’s 50-state emissions legal full-length headers for 1978–1987 GM G-bodies allow for increased exhaust flow and serious power gains.
Whittier, Calif. (July, 2014) – GM’s G-Body platform was the foundation for many of the most memorable and legendary automobiles that hit the streets during the 1980s. The Monte Carlo, Regal, Cutlass and El Camino each had their own unique style and packed some of GM’s most potent V8 engines of the era. Thanks to the platform’s light weight and venerable small block power, G-bodies have become a favorite of gearheads across the country. Now, Hedman Hedders offers a line of smog legal headers for ’78–’87 GM G-Body cars that help enthusiasts coax every ounce of power from their engine while not running afoul of “Johnny Law.”
Hedman’s full-length headers are engineered to deliver maximum exhaust flow while maintaining the factory catalytic converter locations and A.I.R. injection, making them 50-State emissions legal under C.A.R.B. EO#D-167-33 for vehicles equipped with 305cid, 307cid and 350cid V8 engines. Even with their state inspection-friendly status, these headers deliver performance that is far from stock, helping unlock the true potential of your G-body’s small block engine. Hedman builds these headers with 1 ½-inch primaries and a 3-inch ball-style collector, and are available in either Hedman’s Standard Duty or Ultra-Duty ELITE construction. Standard Duty headers are built using 18-gauge mild steel primaries, while the Ultra-Duty ELITE headers feature bullet-proof 3/8-inch flanges and thick-wall 14-gauge primaries. Each set comes complete with header gaskets, bolts and header reducers that easily weld to the car’s exhaust system for a durable, gasket-free connection between the headers and the rest of the exhaust system.
Standard Duty headers for ’78-’87 GM G-Body vehicles are available either in an uncoated finish (#68311) or with Hedman’s HTC polished ceramic-metallic coating for protection up to 1,400-degrees Fahrenheit (#66311). The Ultra-Duty ELITE Series headers are coated with a matte finish version of Hedman’s HTC hi-temp coating (#61318). Mounting hardware, instructions, and the mandatory E.O. sticker for your engine compartment are also included. For those looking for more power from their emissions-exempt vehicles, Hedman also offers these headers without A.I.R. injection (#68310, #68316 and #68318). If ground clearance is an issue, Hedman offers mid-length and “shorty” style headers for applications where maximum ground clearance is required.
All Hedman Hedders are manufactured in the U.S.A., come with a factory-backed Lifetime Warranty against defects, and a five year warranty on the HTC-coating. For more information, call (562) 921-0404, visit www.Hedman.com or email [email protected].

Very nice. Since Edelbrock and Hooker have discontinued their 50 state legal shorty headers the only option has been to find a set out there on the used market. Yea, used headers….
First time someone has made a legal full length header for these cars, good job.
