Here is what I dont understand. You are willing to hate on Trickflow because of your bad experience but I dont think you have ever once mentioned who your failed built motor was purchased from. Why not? I mean if you are making statements about your experience with TF why not make the same statement and mention the built motor supplier?
It reminds me of another person I dealt with about two years ago that contacted me about a spun rod bearing in his new build that was done by another shop. I spent alot of time on the phone trying to help diagnose the issue and help him figure out a solution and when he told me the story I was amazed he wouldnt say anything about it publicly, especially since he swung so hard for this company on Facebook and here. After spending about 35K with them they told him to pound sand. The mentality of this has always amazed me... Anyway..
Trickflow failures.... Lets discuss... Actually let me toss out my unpopular to those who have had failures opinion...
I will preface this by saying yes, Trickflow has had some failures that were a direct result of product failure. However the three failures I have seen in person were all due to improper installation procedures for the camshaft.
You see most people do not have the tool that compresses the valve spring to install the follower after the cam has been installed, so they install the followers, find a roughly "neutral" cam position and lay the cam in place, then tighten down the cam caps, hopefully torquing them to spec and that is the absolute worst way to install a cam in a cylinder head. The proper way is to have the lifters in place, install the cam with no followers in place, torque the cam caps and make sure the cams spins freely in the head before you use the tool to compress the valve (with the piston down) to install the intake and exhaust followers. (cam lube everywhere of course) Doing it the wrong way does not ensure proper cam cap torque and can "bind" the valve train which will result in kicked off followers, valve/piston damage etc... All easily blamed on Trickflow of course.
Most likely the above paragraph should explain why I have had Zero failures of any Trickflow head in house.
