Angry Engine Problem

I purchased this engine 5 years ago. A 49-53 engine. Have had running on an engine stand.
Starts and runs ok 19in vacuum. When I rev up the engine, It starts running bad. Pull spark plugs and the electrode is shut. Looking thru spark plug hole
Can see where the valve has been hitting the spark plug.

CHAMPION J12YC AND AUTOLITE 216

Wrong Spark Plugs?
