If you have a ZZ4 crate motor or are using ’92-and-later LT1 or LT4 style D-port heads in your street rod, these tight-fit headers are for you. The tight-fit design fits in a wide variety of applications, and the headers have built-in OEM-style donut seals on the collectors so no gaskets or collector reducers are needed. 

  • Compact design
  • OEM-style exhaust pipe connection
  • 3/8” thick flanges
  • 16-gauge tubing  
  • Header bolts and flange gaskets are included

Available in bare steel or with our durable, attractive Armor Hot Ceramic Coating.

  • ZZ4 crate engines
  • 1992 and later LT-1 & LT-4 engines
  • Compact design will fit a wide variety of early street rods
  • Will not fit 1955-1957 Chevys, Camaros, Chevelles or other modern cars with crossmembers under the two center exhaustt ports

Armor Hot Coating (AHC) is a heat resistant, ceramic coating applied to the outside of the header. This coating will reflect heat, which helps retain more heat within the header tube while simultaneously speeding up the exhaust flow. Not only will this coating help you make more horsepower, it also keeps your headers rust-free, looking great, and lasting longer (when properly maintained).  If you are looking for a show-quality finish for your headers, this is it! Our AHC will withstand exhaust temperatures of up to 1300¢ª F. 

  • 1-5/8” primary tubes
  • 2-1/2” collectors
  • 3/8” thick flanges

AHC coated headers will burn and be damaged at exhaust temperatures above 1300 degrees. An excessively lean fuel mixture can generate exhaust temperatures over 1700-1900 degrees. If the coating is burned (which will look like a dull gray) due to a lean condition, it is not warrantied, but the headers can be recoated.

Not legal for sale or use in California on pollution controlled motor vehicles.
