MGB Head Gasket Debate - Payen, Fel-Pro, Lucas, Which do I use??

The MGB comes with a standard copper head gasket that tended to leak coolant on the right side of the engine. The Payen AK660 become the go-to replacement, which is the same as the Fel Pro 21183C gasket. Recently, anyone purchasing one of these gaskets has found that they have changed and are NOT as good! See the video for the differences. Lucas now produces a heavy duty gasket as well.

Outstanding video and presentation.

Anybody finding that the Payen AK660 is still the "good" one with the silicon in it?
