I always disassemble at TDC so that when I reassemble I dont have to adjust anything but the timing, which if you mark the distributor before you remove it (if needed) you can bolt it all back together and not worry about anything.
If you are not currently at TDC, then the cam is at some point in the lift and is lifting the pushrods, which would cuase some valves to be open. ...by the way, those "metal pieces" that push the valve open are called rockers.
Were you at TDC when you reassembled? If not, some of the valfes will be open. All the rockers should be torqued when they are fully closed. I like the go through each cylinder at a time, rotating the crank, watching the valves, and torquing them when they're both closed, then go through a second time and re-torque/re-check everything.
