Few cylinder head questions I pulled my passenger side head to get a broken exhaust manifold bolt machined. Now that i am about to put the head back on i have a few questions....
1)How do I clean the head safely to remove metal shavings from the machince shop?
2)Do i have to set the valve lashing? what exactly is that? i only pulled the head bolts and rr bolts off, didnt mess with the springs or anything else
3)Do i have to get a new head gasket?
btw i didnt notice coolant in cylinder 8when i pulled the head, but now there is a very small amount in it, should i be worried? car ran great before i started tearing down. also alot of coolant came out from the bolt holes when pulling the head, maybe its from that?
thanks guys for your help!

Those pistons look pretty good actually. I would just get some simple green and use a rag to wipe down the cylinders and piston heads. Maybe wipe a WD40 soaked rag on the cylinder walls afterwards.
You MUST use a new head gasket.
You MUST set the valve lash - http://shbox.com/1/4th_gen_tech2.html#adjust_valves
You forgot step one...draining the block before you pulled the head. That's why you got coolant everywhere. I would change your oil, other than that, you should be fine.
Good luck with the rest.

I agree with this guy Mike.
A WD-40 rag will be great, and make sure to get all the coolant out of there. Coolant doesn't compress.
New gasket is a must.
Change you're oil, because you don't want milky oil running through your motor. Your cam will thank you.
Valve lashing is pretty tough, and if worse comes to worse, I can hook you up with someone to do it for you. Tom, Dave, etc.

also to clean up the head go get a sanding block and about 500 gritt sandpaper and sand in a even circular motion! You don't have to get it perfect, but get the majority of the gasket material off!
