Default Rockford Power 500.2

This amp originally had 5NO5HD fets for the power supply. I'm swapping these for IRF3205's. The current gate resistors are 100 ohm which I believe is too high for the new 3205's correct? From researching some other threads, it looks like 47 ohm gate resistors are needed. I'm just looking to confirm this before I go any further with the repair.

I generally use 47 ohms gate resistors when I use 3205s in these amps.
