I thought the same thing. Because of the material the 96-98 intake runners are made from, the EH would destroy it. Most folks get in their and cut the runners out instead because of that very reason. Someone over on Corral has an article on how to do that. I'd ask around over there for specifics. I would question exactly what was EH on that intake. Just so you know, EH and porting is completely different. EH is forcing an abrasive putty through the intake which wears away any particles, obstacles, or anything that obstructs flow untill a certain CFM is achieved. Porting is manually grinding and removing metal generally at entraces and exits because you simply cant get inside runners using a port method.
