Headers on Pontiac V8's are a ROYAL PAIN,especially on T/A's.
The collectors are always bottoming out on speed bumps & replacing BURNT header gaskets is NOT alot of FUN!
You want to buy a set of RAM AIR exhaust manifolds. (GTO D-port style)
Try our HOST here FIRST,(Performance Years)
Price is around $350.00 & worth EVERY penny.
You install them ONCE with steel shim gaskets & that's IT. (NO maintenance issues)
These manifolds are just as effective as headers are on street driven cars & will take you into the LOW 12's if the rest of your car is capable of attaining that speed.
