Update on header mods
last year I had the headers cut and made slip on collectors. Well it
worked good but I could not get the slip on collectors to seal for very
long. Whih caused a lean signal to the ecm ( headers were sucking air
before the O2 sensors). I would have to reseal the collectors about
every 3 -4 months. So checking around I found a water jet company
that could make flanges on the header and collector so they would bolt
together with gasket between them
They did a beautiful job of making flanges so they could bolt together
also made up a dozen gaskets and each gasket is exactly the same
for driver and passenger.
