Q: What is a block hugger or ram horn header? Block hugger headers — also called ram horn headers — are a shorty header design where the primary tubes are routed tightly against the engine block for maximum chassis clearance. They are a popular choice for builds where space is limited or where a factory-like appearance is desired with improved flow over stock manifolds.
Q: What port shape do these headers use? These headers use 1-3/4" x 1-1/2" oval ports, compatible with standard SBC oval port cylinder head configurations.
Q: What is the bolt hole spacing on these headers? The outer bolt holes are 17-3/8" center to center, matching standard SBC head bolt spacing.
Q: What bolts are included? 10x1.5x25 zinc header bolts are included with the headers.
Q: What collector size do these headers use? These headers feature a 2.5" collector.
Q: What material are these headers made from? 304 natural stainless steel with full TIG-welded construction and CNC-machined flanges.
Q: Are gaskets included? Yes. Standard graphite manifold gaskets are included with the headers.
Q: Are these headers street legal? No. These are race-only headers intended for closed-course competition use only. Installation on a street-driven vehicle may violate the Clean Air Act (42 U.S.C. 7522(a)(3)).
