ports? I'm speaking specifically to this image:
 That's a significant difference. I understand the flow rates were measured using a stock head, so I'm curious how much additional flow would be gained by port-matching the heads? Would it be worth the time/effort? Perhaps I missed this in an earlier discussion? I'll be interested in a set without EGR, so I'm glad to hear that's an option.
