can headers really hurt my ws6
Any car will burn the valves if you have a massive leak. Exhaust manifolds can leak due to loose manifold or header bolts. My stepson burned the valves on his S10 because the exhaust manifold bolts came loose and he kept driving it anyway.
If you want to get technical, millions of hotrods and muscle cars have run headers without any problems. You just have to use a little common sense.
Good luck,
Al
