COSMETIC TIP: Skin oils from your hands and engine compartment grime causes
ugly “yellow” spots to appear on the chrome as it “blues” from the exposure to exhaust
heat.
CAUTION! Gloves or other protection should be worn to protect installer from burns
due to hot exhaust components during these final steps!
IT IS CRITICAL that all bolts be re-tightened HOT after about 20 minutes of operation
to prevent gasket failure.
NOTE: HEADERS ARE NOT MEANT TO SERVE AS “EXHAUST SYSTEM SUPPORT
HANGERS”. Additional hangers may need to be added at the time of the installation of
the headers so that THE EXHAUST SYSTEM SUPPORTS ITSELF when the collector
bolts are removed. HEADERS THAT HAVE “SAGGED” DUE TO THE LACK OF
SUFFICIENT EXHAUST SYSTEM SUPPORT WILL NOT BE REPLACED UNDER
WARRANTY!
NOTE: Header bolts should be inspected for tightness from time to time to ensure
optimum gasket life. The bolts will STRETCH some at first due to the exhaust heat, so
they’ll loosen WITHOUT TURNING until they “take a set”. (Bolts hard enough not to
stretch would BREAK!) We’ve experimented with the various “locking devices” on the
market, which prevent from turning. They DON’T WORK on HEADER BOLTS, and
they greatly complicate the process of re-tightening the bolts when it’s necessary.
What DOES work is this:
Go over the bolts again after the first DAY of driving (or about 100 miles- whichever
comes first), then after the first WEEK, after the first MONTH, and then EVERY 6
MONTHS. Our exclusive gaskets are specially made so that the cylinder head
SHOULD begin to melt before the gaskets can burn up. About the only way to kill these
gaskets is to let the headers get loose and then keep driving with a leak.
Due to varying conditions between geographical locations and usage, we strongly
recommend having the engine re-tune at a reputable tune-up shop after the installation
of the headers. Doing so will ensure that you get the maximum benefit from the
installation of the headers.
