The stock headers have their limits eventually. Mainly from cracking and fatigue over the years of use.  What seems to be the best header upgrade available from a longevity and performance perspective?  These will be going on a 258ci TA engine. I've run the Poston stock style on the 109 but I'd say it's time for an upgrade.
