I would sure hope it flows more than an SBM head, that's only a hair less than a 2009-up 5.7L Hemi head. There aren't many other ways to get 300 HP out of 3.6L naturally aspirated while also meeting emissions and fuel economy standards.
I wish the Pentastar platform could handle forced induction that would be awesome in so many ways... that's a big reason you almost never see them swapped.
