intake manifold removal help
So long as one doesn't go crazy with using a wire wheel on the head bolt, there are no issues with the practice. I've done it, along with running a die across the threads to ensure they are clean and have had no issue with either practice. I also run a tap into the block's head bolt threads to ensure they are clean, too.
Given that the threads on the bolts are FAR harder than the wires on the brush...... and it is simply not possible to get anything hot enough to matter..... I think that one falls definitely into the "Myth" category. Far more likely for severely rusted bolts to become sloppy once you clean all the rust off.......
