Hi, I have a 383 and 440 of which both have slight water leaks around some of the header bolts. What is the best sealant to use IYO to seal these areas?
Thanks in advance.
Red RTV Silicone sealer will work just fine. Just a dab is all you need. Liquid Teflon tape also works. Permatex, Loc-tite all make tread sealers. Just use high quality stuff.
