You think those headers have issues
one of the Pantera vendors had a bunch
of SS headers made up for Clevelands (yeah
that is a ford for those you don't know

One of my buddies ordered up a set and the cones
they installed in the collector where the four tubes
meet were off center so far he jumbed in his truck
and drove to the La to get a better set.. they
went thru a dozen sets before they found one that
was right.. also had cracking just down from the
header flanges..
Beware of what you buy and who made it...
worse of all check it as soon as you get it
not 3 years later when you are finally ready
to install them.. I've done that several times.. not good
