Now, I'm far from an expert in this field, so my next question might sound pretty stupid...
Aside from the seat sizes, you're pretty much saying the 2.5L
heads have the same sized intake ports as the 3.0L heads? Why then would the 3L have bigger valves? I do find that hard to believe, but what do I know...
Anybody that knows what they're talking about wanna chime in an edumacate me?
