Lots of good info in this thread:

If you do decide to go with the WOT method, after each "tank", you let the engine completely cool down. Make sure the piston is at the bottom while it's cooling.

I'm currently running a friends WOT method on two engines for the first time. It's very different from Josh's method - but I trust him, he used the procedure on his engine(s) and it's doing extremely well.

There is a certain "leap of faith" you need to take when you do something like this. If it doesn't workout, you'll just have to chalk it up to experience. Yeah, it may cost you some bucks to fix the engine if things go terribly wrong, but what the heck - it's only money.

This the break-in bench I'm using:
