Arouse the DAMPFHAMMER!
Sorry to read about the damage. Did you inspect the bearings of the roller rocker and the cam towers too? Do you have an idea what could cause it?
Mechanically they would fit. Do you have a part number for comparison?So i quess the question is does K20A3 ex cam fit ?
Please see the table here: https://en.wikipedia.org/wiki/Honda_K_engine#K20Aand wich cars use K20A3 and A4 motors, besides CRV
