Piston Flip

Howdy, gang.

I've been watching quite a few of his videos with a grain of salt in mind. I am certainly not a professional mechanic, but rather a hobbyist at best. Some of his videos have good information to someone who needs a visual. Like a child with a comic book in hand watching Justice League, I watch his videos trying my best to decipher his explanations with the help of my manual. The question is, should I use him as a safe and reliable source? The video that made me question was the ol' "/6 piston flip," he is known for promoting. Worth a shot? Or no?

*Uncle Tony, if you're here, no offense given. Just looking out for my ride. Pleasure to have you on the thread!*
Sounds to me as if you're trying to stir up already muddy water.
