Ticking noise, 383, can't locate the source

ticking, popping out the exhaust , are you sure the cam isn't or lost a lobe.

It has never popped out the exhaust, always ran great. I had a fuel pressure issue last year, and now this.

I'm not sure about a lobe.
It just makes no sense that taking the rockers off and putting them back on would make a wiped lobe show itself.
