1990 Grand Marquis 5.0 EFI motor - need input.

Okay guys.. here goes.. I need to know the difference between an HO and non-HO 5.0 EFI motor. Guy has a 1990 grand marquis with like 86k miles on it and says I can drive the car to see that its a good running motor. I know the intakes face the other side..(why?) but other than that looks exactly the same. Says if I come pull it out I can have the entire motor manifold to oil pan for $250.

So whats the difference? Would it have a forged bottom end being a 1990 motor? Where the heads just different? Should still be a roller cam motor? I don't see a 1990 302 being a non-roller.

Can someone please tell me if buying this motor as a backup block/motor thats in running condition for $250 being a good deal? I want to use it for mock-up reasons for a project with my motor but also as a back-up block/motor incase mine fudges up.

Thanks for any insight guys. I know its not an HO but is it a good deal?
