Ok a couple of weeks ago I blew the head gasket. Had hydrocarbons in the coolant. I pulled the head this weekend and found that the rear cylinder had about 5mm of coolant sitting on top of the piston, and the associated valve section on the head is rusted (obviously this is where the leak is). So I'm wondering, is the block goign to be OK? Can I just get the head re-worked assuming it's not cracked, put it back together and move on?

Also, anyone know where I can get new head bolts? One or 2 of them were very rusted. Another reason the block could be trouble I guess as some of the threads are rusted out. Thanks for any advice!!!

Here are a couple of pics:
