Flowtech 11110FLT Long Tube Header Black 64-67 Chevy II Nova SMALL BLOCK CHEVY

11110FLT Flowtech Long Tube Header - Black Paint. Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16 flanges with sealing rings for a leak-free seal. This header is coated in a high heat resistant black paint for a stealthy appearance.. Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. 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. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Fuel Economy From The Engine.
