All your original parts will fit the block. You'll need to work out the compression ratio. You'll need aftermarket management to be able to set it up properly. Take a good long look at the 2.1 stroker option, built into your original block, which can be a better choice for a whole lot of good reasons.

Yes, your current set up will be plenty good enough for running it in.
