Trick Flow small block heads

This is pretty interesting. The first I was like oh my God they're way too expensive. Then man I have to have these one of these days. now I'm thinking hold on a second maybe they're not all they're cracked up to be. But then again everybody says how great they look...

So, an honest question for you, would you spend your own money on these before knowing a combination that they work with? If so, what kind of combination would you run. I personally work too many hours, and need to get this engine right the first time, because I can't afford to replace them if they do not work. As a budget guy like yourself, I would think that you would understand that more then anyone else.
