Difference between LA and magnum head gaskets

Seems like the big difference as I remember was that the head gasket had a tab that keys into the intake gasket to keep the intake gasket in place. But the intake gaskets that Rumble showed didn't have the tabs like I remember so maybe that isn't something they are doing anymore.

Looks like the Magnum HG also has guides for the pushrods, probably just to make assembly faster. Doubt they have any function after the rocker arms are bolted down.
