So, does that mean it is or is not a ho engine? Forged internal rather than cast?

The is no such thing as an HO engine for a Merc 454. Its either a Magnum engine or its a regular 454/7.4. The 454magnums have all good forged internals.
The 350 hp rating is at the prop. Its rated 365hp at the crank.
