Okay guys I plan to make some money this summer so i can buy some PI Heads for my 96 GT, My question is powerheads.com sells PI Head swap kit for $1300 and claims a gain of 65 rwhp. They also offer another kit with port and polished PI Heads for $2200 that should give me and additional 110rwhp. Should I spend the extra $1000 and get the port and polishing or should I juss stick with the base kit that adds 65rwhp?
