New carbon steel bolts ? Anti-seize?
After so many hours and $$$ of removing broken bolts we replace them with the same grade bolts?
Considering the frequency and expense of this issue ,it is surprising there isn't a little more interest in using the inexpensive, simple to install s/s stud kits mentioned earlier.
If intelligently installed, s/s studs will work perfectly for more many decades.Carbon steel bolts - not so much.
It would be poor engineering practice to use anti-sieze in this situation. It will complicate the choice of effective torque settings for the bolts because it acts as a lubricant. IMHO the correct grade of Loctite is better choice for exhaust bolts, studs & nuts( different grade for each) .
Loctite effectively deals with the conflicting issues of heat cycling, dissimilar materials, vertical installation, vibration and ability to remove the studs.YEMV.Suggest a visit to the Henkel tech section.
