The next to last post in that thread by AndyZ needs paid careful attention to. He's dead right. Plus, the ring pack on the stock pistons is also not far enough away from the piston crown to run a lot of boost. The KB pistons for example, have the rings located much further down the piston to keep them out of harm's way. That said......that's a good thread. Seems they agree with what I've been saying. You can do it, but you need to watch the tune.
