Thanks to all who respond. I am thinking of buying a set of pi heads and i am wondering if anyone has ever done it for a 98 GT? I currently has an S Trim Vortech supercharger installled and was also wondering if anyone knows where about my horsepower is now and if i do the swap.. I am pushing 7-8 pounds of boost generally, Thanks

From what I understand, your threading a thin line when you boost after doing the pi head swap. The swap should put your compression around 10.5:1 which is kind of high to add boost too, ecspecially on stock internals. If you do go ahead with the charger, and swap, make sure you get a very good tune to help improve the longevity of your motor.
