blown head gasket, part 2, creativity

Hi, in this post you will see thing which took place after removing head from engine.
Remember exhaust headers?
Separating them from head was easy, real challange was these 3 nuts:
Scraped oil slime from valve cover:
And hurray to dishwasher, yes dishwasher:
You could smell engine oil from dishes two days after, but this was worth it:
Next was few bits from engine, but this time hand washied:
In order to have head machined, I had to remove all valves and stuff.
First was this bar, which was easy:
Second were valves, but how without valve spring compressor? No plans, just plain creativity and this pile of junk:
Fast turned in something like this:
It turned out to be a realy good tool, but those valve locking washers were stubborn as hell.
In the end I removed all valves and sent head to be machined.
