I've had more people boohoo about the stuff, if in doubt use silicone.. I use hondabond for anything aluminum!! Best shit ever!!!!
Headers on all 2,3,and 4 valve cars I used high temp silicone on gasket and bolts, never had leaks or bolts fall out.. Flywheels, drive-shafts red loctite.. List goes on, I know where it's needed!! LOL
