That looks AWESOME MAN. I'm glad you used my method. haha. I guess when I made this account here I typed an extra "07" on the end of my sn.
I did most of all my engine parts. I didn't spend near as much time on it as you did though. But it still turned out nice. You can pretty much use anything with the cleaning process. At first on my UIM I used engine degreaser which worked really well. Then once I got most of the dirt/grime off I used soapy water.

These are some pics of the engine once I cleaned all the parts (Water pump housing, Front cover, LIM, etc) I'll try to get some "before" pics so ya'll can compare.
