Sump pan gasket recommendations

[Lee]

I read with interest that Mark Worthington recommended the blue Felpro silicone sump gaskets which are fitted without sealant.
Any other recommendations, and also can anyone confirm part number for my application. G351 SVO as in the pictures.
Thanks very much

It depends on the oil pan. I love to use the black rubber gaskets that came stock on 5.0L, but they leak with many aftermarket pans because the pan rail stamping is not accurate enough.

Personally, I'm a fan of the Mr Gasket seals that use metal spacer washers bonded into the seal material to prevent overtightening. They seem to keep leak free even with the extreme heat cycles of a race engine, and do not seem to break down as some of the others do.
