Broken timing chain ??

[jetspeedfreek]

Greetings,
Just put a new Roller timing chain set in my stock '69 429. As fate would have it, it somehow snapped the fuel pump arm off, and wedged the piece in my new gears . I figured this out after the engine wouldn't start after numerous attempts. Bottom line is that I cranked the motor over and over after the timing chain had snapped. I'm hoping I can just put a new chain on and go, of course after the cam is lined up. My question is, did i do damage to the valves and or valve train? Do the pistons hit the valves on these old 429s or have Motor Gods spared my dumb **s?? Any help would be great.
