Ok, so Ive done a bit of poking around here and have been talking to Esslinger Engineering here in So Cal regarding the construction of a 2.3 litre Mustang ITB motor. The question regarding the heads immediately came up. According to EE, the older 4 plug heads are better flowing and are better for a racing application than the newer 8 plug ones. They were saying that folks using the 8 plugs do so because they have to, not by choice. However, we in IT do have a choice on this matter and I was wondering if anyone had some input. Are the 8 plug heads more restrictive than the 4 pluggers? What is the advantage that the 8 plugs are supposed to have over the 4??
