Ok, sometimes I place too much of my self worth in how cheaply I can do things that otherwise would cost a lot. Hence the following question:

I have time, tools, and a cheap disposition: is it worth trying to port your own heads? If so, where can I get info on how to go about it?

(I have a garbage can full of degreaser, just so I don't have to pay to have my blocks cleaned.......I'm so ashamed )
