Essential amino acid requirements

I'm reading that without an adequate balance of the eight essential amino acids, the body is incapable of synthesizing tissue from protein. Instead, surplus protein is reduced to simpler proteins for synthesizing non-essential amino acids and/or converted to glucose and potentially to fat.

Another poster suggested that an excessive surplus could also result in the formation of ill-defined muscle with the potential to break down more easily. (Bulky versus lean muscle).

What ratio are the eight essential proteins needed in? Do these ratios change in repairing muscles under extreme duress, i.e. in weightlifting?

Where can I find reference for the levels of the essential amino acids contained in common foods? My particular interest is in vegan foods.
