any main differences, would they still bolt up to a 2000 5.3 truck block?

Yes they will still bolt up.

Any reason why the Center bolts are the ones i should go with? Will there be any differences in them, like will my coils still bolt up in the same spot on the valve covers

they are better engines, a little more developed and such. as with any engine when it first comes out, the first year or two had a few problems.
