The headcover bolts are the ones.
I think that one thing gets forgotten, that needs to be stressed. We mentioned getting a manual and a CD, right?
The next thing is to "Read the Manual". Sounds, kinda smart ass, doesn't it? Nope, not intended to be. Just the truth, in point.
The manual tells you to use specific tools for certain tasks. One of those tools is a Torque Wrench. Those bolts will break when they are over tightened. They only need about 8 lb/feet of torque, and almost all of us can do that with our little finger and a wrench.
They also tend to get stressed and they may break later if over torqued on a previous job.
If you have any doubts...buy new bolts.
Ready for a shameless plug? These come off my CD
I guess that no one can say that I haven't "been there", either, so now you've been warned...
