RE: 4AGE Big port head failure
Bent cams are very rare. There are ways of checking - easiest is to bolt the camshaft into a bare head and see if they rotate smoothly. Other is to use "V" block to check for any wobble during rotation.

Most likely bad luck. Did the head and cam run before the rebuild? Or was the head and cams a used part you picked up to build your engine?
