Engine exploration...., Is this engine any good? Options

Hi all,
Well after pulling the engine several weeks ago and asking retarded questions about push rod tubes, and oil geysers, I done n pulled the cylinder head off of #3 and #4. Having done this I was finally able to learn some things.

1. My cylinders are 96mm in dia and 76mm stroke, (I get 2.2L) Yeah! (IMG:style_emoticons/default/driving.gif)

2. My engine doesn't look like the prestine engines I see on all the Discovery Channel TV shows like Rides and Overhaulin. (IMG:style_emoticons/default/sad.gif)

So my questions to those who know.

1) Is it normal to have all this black cryosote (sp?) looking stuff all over the pistons and valves?

2) Should I just put this thing back together and quietly walk away and call the engine toast? or should I clean all the crude off and try and put it back together?

3) My compression numbers are:
Cyl #1 100
Cyl #2 85
Cyl #3 100
Cyl #4 75


4) Is this engine worth fix'n??
