[SLOW 97]

The intake will not fit the '99-up heads. The ports on the 96-98 heads are oval and the ports on the PI heads are rectangular. If you swap heads you musta swap the inake manifold as well so the intake ports will match up. There are numerous kits out there to do this and they come with all the parts you'll need for the swap. There is a kit from DTA racing that comes with all the parts you need and the heads are ported and it's only $1500. You can contact Mustang works user SD WHEELER for help with this. For $1500 this kit will net you 50+ rear wheel horsepower. The PI-heads are defintiley a must for the '96-98 GT's. Once I get the extra cash the'll be on my car!
