Info

Info

If you have a ZZ4 crate motor or are using LT-1-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. 

These headers have an attractive Armor Hot Coating, but are also available in bare steel. Header bolts and flange gaskets supplied.

Warranties

Warranties

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.
