I'm not pushing anything. If you think this discussion is about heads you're sadly mistaken as his heads were used to prove a point that you now want to totally ignore. If think airflow is everything than how come Dan makes power with the stuff you think isn't worthy of your time. There's more to making power than just airflow. If you ignore the fueling aspect then an engine is just an air pump and you need bigger heads. Oh and if you build an engine with all that exotic stuff and it doesn't make the power you think it should then it needs bigger heads....
