Patriot was a cast of cnc ported pi heads. People used to rag on them but no one had any actual experience with them. The thing is, I bet there is room for improvement in the design of the 2v head. In your opinion, do you think it’s the small displacement that limits the power output or the intake volume? I don’t see why a 2v head couldn’t flow similarly to 4v heads, given a redesign of the water jackets and more intake runner volume.</p></blockquote><p></p>
