Car doesn't run right after valve cover replacement.

So here is the story, i was changing the old bolts of my valve cover. So i remove them, and as i was wrenching off the pvc, I crack the valve cover. I thought no problem ill continue.. .
i finish up wrenching the new bolts, and i go and start the car. It doesnt start! It sounds like the battery is dead, even though its only somewhat 5months old. So i'm thinking, maybe its the valve cover, since i crack it and the pcv does not screw all the way in, and its very loose (almost no contact). So i go to my local pick and pull, and i get a new valve cover. I drive home, take of the old one, install the new ones. Evrything looks good. I start her up. SAME PROBLEM! I check all the hoses, evrything is connected. This is when i start to give up and i close the hood. But i tell myself, lets give her one more chance.. than she starts! but.. she is running like sh2t. The engine is shaking like if there is a dog in there, and the car sounds like an old muscle car with some massive cams. I try to rev her up a little, and she stumbles. check engine light goes on for a minute than turns off.
what do you guys think?

If the PCV valve hole is stipped, yes. Don't torque everything so tight...

So here is the deal. I order a new vc, gaskets and install them. The car started just fine, ran like a champ. The thing the threads on the head are badly damage (5 of them). So it leaks like crazy and goes all over my injectors and manifold. Should I buy a heli coil kit and re thread them?

Yes.
