Description

The Header SBC Modified 1-5/8in 1-3/4in Long from Schoenfeld is a purpose-built performance header set engineered for small block Chevy engines seeking enhanced exhaust scavenging and increased horsepower. These headers are the choice of serious engine builders and street performance enthusiasts who demand improved low-to-mid range torque and peak power output. Unlike restrictive factory manifolds, properly sized primary tubes and a tuned collector design work together to extract spent gases efficiently, allowing your engine to breathe freely and perform at its peak potential.

These headers feature stepped primary tube sizing with 1-5/8 inch and 1-3/4 inch diameters that match cylinder firing sequences and exhaust velocity curves across the RPM band, preventing backpressure losses while maintaining scavenging efficiency. The 3-inch collector consolidates exhaust flow smoothly, reducing turbulence and thermal stress on downstream components. Constructed from heavy-gauge steel with durable black powder coating, the Header SBC Modified set resists corrosion and heat discoloration under sustained high-temperature operation. The pair includes all necessary gaskets and mounting hardware, simplifying installation and ensuring a leak-free seal at the cylinder head interface.

Small block Chevy enthusiasts—from bracket racers and street rod builders to performance crate engine installers—benefit from this header design's proven track record of reliability and power gains. Whether upgrading a classic 350 or carbureted 383 stroker, or integrating into a modern EFI conversion, these headers bolt directly to standard small block Chevy cylinder heads and mate cleanly with typical collector-to-exhaust piping. Dimensions of 21 x 10 x 37 inches allow fitment in most engine bays with modest headers clearance, though bay configuration should be verified before purchase to avoid interference with steering components or radiator hoses.
