at least a few people have done this and it has been done safely so far,
I'm pretty sure you will get cels from removing this but i forget the evidence thread of this., so i'd suggest a way to delete the cel's for inspection
I guess ask yourself if its worth messing around with the engine to remove something that perhaps saves some lb's but has no performance gain either way...
if your going to do it i believe buschur or.. meld was it? some people were getting some block off plates together.
