Yup.
The spider and hardware, the lifter retainers, the cam retainer and hardware, and perhaps the roller lifters and pushrods should be re-usable. The lifters should be pulled apart one at a time for cleaning and inspection.
If you had a good block, preferably with the spider bosses drilled 'n' tapped, and the cam retainer bosses having the same spacing as the core engine...you're all set.
But perhaps there's nothing wrong with the pictured block that a trip to the machine shop wouldn't fix. Bore, square-decking, maybe align-hone, following a trip through the jet-wash cabinet or shot-blaster. Check for cracks. Polish or grind the crank, check the rods and recondition as needed.
