Unless this amp has an unusual drive circuit, there's virtually nothing other than defective FETs that will cause the gate resistors to burn.

'Dead' and 'one side and the other side' isn't very specific. Precisely what do you mean? Be descriptive. It would be best if you posted a photo of the board as it is now and marked to show what you mean.
