All the rocker arm nuts were replaced (2 of the bolts were stripped) and two of the pushrods were worn where the rocker arm contacts them to the point they had to be replaced (looked like the rockers were "cutting" into them ???) This combined with the broken valve spring causing a dead miss on #4.

I had the same thing happen on a 305 and the cam lobes were also wiped out.
I know you said it runs good now, but I'd keep an eye on that cylinder.
