Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. Please call Flowtech tech services at 270-781-9741 for additional information regarding ceramic exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.Details:Air Injection Tubes: NoBolt size: 3\/8-16 x 3\/4Bolts Included: YesCARB (California) Compliant: NoCatalytic Converter Quantity: 0Collector Attachment: 3-Bolt FlangeCollector Diameter: 2.50 InchCollector Port Diameter: 2.50 InchCollector Reducer Included: YesCollector Reducer Outlet Diameter: 2.30 InchColor: BlackCylinder Head Flange Thickness: 5\/16Design: Block HuggerDrive: 2WD, 4WDEGT (Exhaust Gas Temperature) Port: NoEGT Port: NoEmission Code: 4Engine: GM Big BlockFinish: PaintedFlange Thickness: 0.3125 Inch, 5\/16Gasket Or Seal Included: YesGrade Type: PerformanceHeader Finish: Black PaintHeader Series: Street RodHeader Style: Block HuggerMaterial: Mild SteelMounting Hardware Included: YesOxygen Sensor Port: NoPort Shape: RoundPrimary Tubing Diameter: 1-3\/4, 1.75 InchProduct Type: HeadersQuantity: Sold as a PairSheen Level: SatinTube Material: Mild SteelTube Wall Thickness: 16 Gauge\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComputer-controlled mandrel-bent tubing for smooth exhaust flow\u003c\/li\u003e\n\u003cli\u003eSturdy 16 gauge tubing\u003c\/li\u003e\n\u003cli\u003eTight-tuck design for narrow frame rails\u003c\/li\u003e\n\u003cli\u003eEasy installation - can be used with stock motor mounts\u003c\/li\u003e\n\u003cli\u003ePrecision die-cut exhaust port flanges\u003c\/li\u003e\n\u003cli\u003eEngineered and tested for a leak-proof seal\u003c\/li\u003e\n\u003cli\u003eAll necessary hardware included for a complete installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eUniversal Block Hugger Header: BBC 396-454, Tube Size 1.75\", Collector Size 2.5\",\u003c\/p\u003e","brand":"Flowtech","offers":[{"title":"Default Title","offer_id":51827935347000,"sku":"F00M 11030FLT","price":331.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/425677998.webp?v=1778810489","url":"https:\/\/store.motormia.co\/products\/block-hugger-hdr-bb-chevy","provider":"MOTORMIA","version":"1.0","type":"link"}
