WAY better heads out there anyways. At least I know I can put these heads on out of the box with out any worries, unlike some that we all know. For my needs these heads fit the bill perfectly and if I decide later to go faster they can be ported by IMM who I am very confident in, some people run 10s and faster with them, My Dart is all street and when I'm done I hope to be able to run low 12s high 11s, And yes I like iron!
