I find the periodic re-tightening of header bolts a PITA, especially trying to get the one under the power steering assembly and no.8 (nearest the firewall passenger side) I know Summit sells them, and they aren't cheap. Are they worth it? Is is worth using them on the collectors too?

Whoops yep those are the ones Is the fact that they don't rust a negative one? Hopefully I won't have to take them off after putting them on so the clip shouldn't be a problem. Thanks.

Those are the greatest things around. Had them on for over 2 years and never touched them since. Never came loose. They are definatly worth the cost.
