Trick flow noob ?s

Regarding being ready out of the box, I haven't heard/seen any reports of significant issues with the TF heads that would have caused a performance or reliability issue. I will also tell you that they were assembled by human hands and that person could have been having an off day while doing yours. It's about $75 to have a shop inspect them if you aren't capable or equipped, which is not bad insurance. A lot of guys with more experience than me say they will never run any assembled head OTB without having trusted shop look at them, and there is probably a good reason for that. Like Clint Eastwood once said, "do you feel lucky?"
