Header Adapter Kit shown for Hooker Comp. Headers #5903
TTI part # AD-HOB30903
NOTE:  Header adapters were designed at TTI utilizing new
unmodified Hooker, Hedman and Thorley headers.  Precision
tooling-fixtures were designed to insure exact replication of
each different adapter.  Should your adapter not fit your header
properly due to a mfg. variation in your particular header, it
will be necessary to modify the adapter to fit your particular
header variation.
Adapter sets include:  Correct aluminized bends for header application, gaskets & hardware.
