I'm looking to possibly put a pair of rebuilt heads on a car. It's a 1986 Pontiac 6000 STE. The engine is the multiport fuel injected 2.8L V6 which (I'm pretty sure) was a special high output model made exclusively for the Fiero and 6000 STE. Can I just put any 2.8L heads on there, or are they special for that engine?
