Rearend Gasket Covers Which One?

[68Formula]

I'm looking at two different gaskets. Which one is the best? One is paper the other cork/rubber.

FEL-RDS55028-1 (http://store.summitracing.com/partdetail.asp?CP=1&part=FEL-RDS55028-1&N=700 0&Ntt=MRG~64 or MRG~84B or FEL~RDS55028~1&Ntk=KeywordSearch&rsview=sku&Ns=)
MRG-84B (http://store.summitracing.com/partdetail.asp?CP=1&part=MRG-84B&N=700 0&Ntt=MRG~64 or MRG~84B or FEL~RDS55028~1&Ntk=KeywordSearch&rsview=sku&Ns=)
