Welcome,
Check out Kodak's tech pubs for a start.
Use the search function here for RA4 too.
You can process 2 ways:
I use Kodak RA RT developer replenisher so what I say is for that.
Tray 68F / 20 C
Develop 2'
Blix 2 - 4 '
Wash 4' - 10' at up to 25 or 30 C.
Dry
Drum 38 C / 100 F
Prewet 30"
Develop 1'
Stop 30" (1 - 2% acetic acid)
Blix 1.5 - 2'
Wash 2 - 5'
If you use developer (or replenisher + starter) you can only really get good results at 100F and you must use the EK recommendations for time.
Have fun.

I'll add mine for drums at 20-22C, or room temp. Kodak RA/RT chemistry no starter mixed with the developer.
Beseler 8x10 drum 70 ml of each
Prewash 30 sec
dev 2 min
stop 2% acetic acid 30 sec
rinse 30 sec
blix 2 min , usually 2.5 as I am in no rush at that point.
Wash 5- 30 min, most of it just sitting in a water tray.
