Good reply. You’re on top of it. My point exactly.
But is there a change form going from an LA head to a W9 with its superior head flow and altered valve angles? Or does it really matter? Since everyone likes splitting hairs on this (& other subjects) let’s split hairs here!
IMO, in a daily driver like Dan wants and many other applications, it’s just not worth it. Racing for the money? Let the dyno testing begin!
