So uhhhh....what's your question?

Did you search this forum? Anyway, check out these recent threads. Two of them are regarding bent valves, one is a rattling caused by a crack in the header.

sorry about that,I was just wondering if a bent valve would sound
like that and cause it not to start again.

Not sure if a cracked head would cause these kind of a problem. i have never experienced anything like that or read about anything like that.

It may be best to remove the valve covers at this point and see what you have under there. If everything looks good pull the coil wire and crank the motor over to see if everything is moving correctly.

Never heard of a ford V8 breaking a cam but you never know. Just a thought.
