We have completed retooling from scratch to produce our concourse headers. We have filled our backorders and are trying to keep 2-3 sets in stock at a time.
Our jigs were built and checked with 2 set sof original headers and a set of our previous headers. 2 sets of NOS headers were also studied.
The flanges are angle ground for head bolts and great effort went into making sure the port shape at the head flange is correct.
These headers are now made 100% in Green Bay, WI.
