Question Header Gaskets Bison or Copper

Can some tell me which Header Gaskets seals the best.
The Copper one is from Mr. Gasket they have lip on the the port holes. I have never used the Copper one before. Which side does the Lip fit? The Engine or Headers.

The other is the new style from Bison, they are thinner than the old ones.
I used Bison gasket before and they were thick ones and never leaked for 13 years.
My Car is a 68 LeMans with a 350 engine, Headers are Hooker long 28" ceramic coated.
Please let me know if you need more info.
