I think Katech released a video where they insisted LT-valve guides were pretty bad from the factory, like the LS7-problem. I haven't noticed that statement from anywhere else, but I'm no expert. I also find it strange TSP will still sell heads with issues they KNOW but don't correct. Maybe I'm not understanding that correctly, but I assume that a big player like that would take care of all the deficiencies, like it seems like a company like AI (apparently) does.
This just sucks though. I'm sorry for your troubles.
