If I recall the sealant used on my exhaust flange to head was the color grey and seemed as though it had hardened. Not like a silicone hard but spongy but hard like glass. This same sealant may have been used on a fitting going into a water passage of the intake manifold. I mean the headers were stuck to the head with no bolts and with a few bumps they seperated. There was hardly any residue to clean off and whatever they used sealed excellent with no leaks.
