Please translate this flow sheet!?!

O.k. After looking at some pictures of how the pro's do it it's apparent to me how much I suck. I'm almost embarrassed to post these. So don't be so hard on me.


The thing that gets me, is the guy that did the flow chart helped we with the heads, and said they were "fine", and I built him a small web site for it. Why do I always feel like I'm getting screwed?

Are there repairable? At least they aren't worse then stock!
