Will this servo handle continuous heavy steering loads?

The torque ratings indicate it can cope with sustained steering loads on many vehicles, but pair it with appropriate horns and check temperatures during prolonged severe use.

Are there recommended upgrades to improve durability?

Upgrading to hardened steel servo horns and ensuring secure mounting with quality screws and grommets will help the BLS451 maintain precise operation under heavy stress.
