Hmmm ... I'd lay money down that is what caused it. Especially since it is one of the center cylinders. Hopefully the piston did not smack the valve.

One time a guy dropped off an old Dodge 225 slant 6 engine to be rebuilt. Long story short ... after bringing the head back three times with stuck intake valves, and complaining we made the guides too tight, he finally flushed out the fuel system. Problem solved. The smell & varnish on the valve stems told me instantly what happened but he was too stubborn to listen.
