Sump gasket advice please

[Motown Junk]

Fitted new B&M deep sump pan to my transmission on my old Camaro, followed instructions to torque to no more than 12 - 13 lb/ft (actually did 11 - lb/ft with a proper low range torque wrench) and the @#$!ing gasket split!

Obv going to get new gasket, but have a choice of another B&M cork one or a thinner Fram black one - which one?

Also any suggestions at what torque settings I should use?

Yours, hair-matted with ATF,

Keith.

Just been and tried 11 and it does not feel excessive.
What material is the other gasket?
Did you grease the cork gasket? If you grease them they can slide and find where they want to sit without tearing.

More importantly, what are the fixings? 1/4" 5/16" - metric ???
