Kinda new to mustangs, just bought a '96 GT 2 weeks ago, and many of my stang-owning friends said that I should get PI Heads, same ones found on the 99+ Mustangs...I've been searching online for a while now, and haven't found a good site to purchase them from. I also think that the mere ~50hp gain is not worth $1300.00. Just need some tips on where to buy them, how much you paid, and where I can get them installed, because i do not feel "up to the challenge" of installing them myself. I'm 16 anyways, don't know a TON about cars yet. Im in the Detroit area, so anyone from there please respond...Thanks alot Stangers!
