Need p/n 440 HP exhaust manifold flange gasket

Hey guys,

Picked up a fel-pro exhaust manifold gasket kit and the exhaust flange to manifold gasket was too small. Who makes the best (longest lasting) flange gaskets these days? If you have a part number I'd really appreciate it!

Thanks!

napa/walker has the fiber gaskets by size in the back of there exhaust book

These have worked out well for me.
