I am doing it as we speak; 4 day version with some adjustments.
Competitive lifts without much assistance work. The frequently of the training the lifts allows the body to adapt to the work load so you can do more volume in each workout, high volume= higher total.
Some like and respond to high volume etc, some don't. Only one way to find out. The best training program will be one developed by you for you so I would try it and see.
As for your numbers they are pretty good and you will improve especially if you have been training BB. They may take a hit in the short term as most do not squat to proper pl depth, pause the bench, and i would re-set your deads when you do them too.
My only suggestion would be to use numbers ~ 5-10% under your max to start.
