NOTE: The backside of the driver's side port flange will possibly need to be relieved/notched to provide clearance to install the engine oil dipstick tube. This can best be accomplished through the use of a rotary file equipped die-grinder, a 4"-4.5" angle grinder, or a rat-tail round hand file.
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. Hooker
recommends using cast iron exhaust manifolds
or old Headers
to break in new engines to avoid coating damage. Please call Hooker
tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker
does not recommend the use of header wraps as this will void the warranty.
