SBF IMCA Headers 1-3/4in - 1-7/8in

The SBF IMCA Headers 1-3/4in - 1-7/8in by Schoenfeld are designed specifically for small-block Ford racing and high-performance street applications. These headers are engineered for IMCA (International Motor Contest Association) competition and bracket racing, where every fraction of horsepower and millisecond of spool time is crucial. Whether you're building a competition cruiser, drag racer, or weekend warrior, these headers provide the performance needed to stand out.

Schoenfeld's headers feature an optimized primary tube diameter ranging from 1-3/4 inches to 1-7/8 inches, balancing low-end torque response with peak RPM power delivery. The stepped tube design minimizes turbulence and maximizes exhaust gas velocity, promoting cleaner scavenging and reducing backpressure at high RPM. This robust construction ensures durability under sustained racing loads and thermal stress.

Ideal for small-block Ford platforms running IMCA-legal configurations, these headers are the preferred choice for dirt-track racers, asphalt bracket racers, and engine builders seeking maximum bolt-on performance gains without extensive cylinder head porting. Their design and engineering make them a reliable option for those looking to enhance their racing capabilities.
