Question:
If I perform three separate injections at three intercostal levels can I report 64420 and 64421 x 2?

Answer:
No you should report 64421 (Injection, anesthetic agent; intercostal nerves, multiple, regional blocks). CPT code 64420 is used for a single injection and CPT 64421 is reported for multiple intercostal nerve blocks even when the injections are at three levels.
