Aluminum heads $ per HP?

Thanks all for your input! If/when I spend that kind of money,I want it to be an educated purchase not a "guess this will work".


I miss reading those magazines(my wife would bring them home from work for me when she worked at TEN). Which of those are still being printed? And which articles do you recommend reading?
Here's a few I had bookmarked.
Search their site, it's there in an article titled something related.
