At Poseidon's request, Alvin "planted" him on the back of the Basilisk.
The way to find a Basilisk's core head was simple...
You just had to follow the main blood vessels along its back to find the location of its most important head.
The Basilisks hadn't chosen the locations of their cores themselves. They had formed naturally.
