Personally, I'd go solid lifter high reving like the LT-1 was when it first came out. I'd use modern parts like aluminum heads and a solid roller cam. There's just something wicked about a solid lifter engine. So long as you don't make it too difficult to remove the valve covers it won't be hard to do the periodic valve lash adjustments. Oh and go fuel injected. It's so much more enjoyable once it's set up correctly.

I would set your original engine aside though. It's also stamped as being an LT-1 not just being for your car. There may be some other restoration person needing a date coded LT-1 and you could have what they need.
