Will this bolt up to the factory exhaust manifold location?

Yes. This header mounts at the factory manifold flange — no drilling or custom fabrication needed. You may need exhaust gaskets if yours are worn, but those aren't included here.

Do I need to do any work to the header before bolting it on?

Inspect the gasket sealing surfaces for any shipping debris and wipe clean. The stainless surface is ready to install as-is — no coating or prep required.

What's the difference between a shorty and a long-tube header?

Shorty headers are more compact and easier to install in tight engine bays — trade-off is they don't flow as aggressively as long-tube designs. For street driving and light performance, shorty geometry works well.
