I did not apply 10 ft pounds, not even close. And thanks for the magnet idea! I actually have some magnets I took out of a hard drive (I used them to reset my dads tire pressure sensors on his Cadillac. The bolts that go into the head are indeed steel. I am happy they are steel because my local hardware store did not have metric bolts in the length of my long ones. And I replaced the aluminum ones that go into the valve cover (for the breather cover) with stainless steel. Finger tight with the bvreather bolts, and 7 to 8 ft/lbs on the rest (the 2 long ones will also hold down the breather cover). Thanks for the help guys.

By the way, I got the broken bolt out! I used a punch to make a hole in the center of the bolt (easy since it is aluminum). Then I took a reverse drill bit (harbor Freight) and drilled the center of the bolt, hoping the bit would grab the bolt and unscrew it (advantage of using reverse drill bit). The bit never grabbed, so when I had a drilled out screw, I took my bolt extractor bits and threaded it in there and with a wrench it threaded into the bolt a bit more. Then eventually it got tight and unscrewed the broken bolt! w00t!

I made a YouTube video, not uploaded yet. I will post the link when after I upload it to help anybody else that does this. Now I know they are one time use bolts. I am not sure why they used aluminum bolts... never heard of that on a car.
