Am debating :

1. Flooded golf cart (Three pairs which will give me about 650Ah.) cost $900 CDN
2. AGM golf cart cost $2200 CDN
3. Li batteries cost - don't have that much money

Considering upgrading the alternators to 120 Amp each but can't get a straight answer as to how much charging current the batteries will take.
The best place to get that answer is from the battery manufacturer but typically standard flooded batteries are specd at no more than 15% of AH capacity. That said, standard alternators will only give about 50% output continuously. Very heavy duty alternators like Leece Neville or Balmar can do the full rated output continuously. Also, 120a alternators will require a belt change. Either 2 V belts or a serpentine belt.
