All heads & barrels are interchangeable for any particular model, but make sure you don't mix heads and barrels of different types, ie. "R" head on an "SE/SP" barrel.

Heads and barrels are identified by "H" or "L" castings in them. Use either a KV3L head with a KV3L barrel, or a KV3H head with a KV3H barrel, and you won't go wrong.

You'll have all the bits soon... a little detective work and you'll know what's what. It's not rocket science!!
