Finishing up taking passenger side exhaust manifold out of 7.3 idit f350(will post pics). Before I put in these new 3/8-16 bolts I had a few questions. Bolts I just pulled out have flange/ washer built in and I was told lock washer will do since new bolts just have head. 10 yr old bolts that came out of truck are just black an no coatings appear to be used(anti -seize burned off?) so wondering about never seize or other recommendations for coating bolts for exhaust manifold.
