TrickFlow Heads?

Trick Flow sets up their heads to be ready to run out of the box according to their criteria do they not? Who would/should be entrusted to check them over and, as some imply, correct them if not run ootb is what I want to know. Very subjective topic IMO. One head specialist says this. Another says that. One guy thinks the valve to guide clearance is fine, one thinks they are too tight. Valve job this valve job that. Spring heights etc. On and on...Who do you place faith in? The concept is to be able to buy the heads and install them OOTB. When we start seeing issues from OOTB installs then maybe worry. All I see in the injecting of doubt. We are not talking Speedmasters or some heads from a shithole head shop.... Stop with the nonsense.:soapbox:
