Those are good lifts. I feel like your squat numbers must be inflated due to gear or squatting really high. I don't see how you could squat 655 and only pull 520.
Yeah, I'd obviously go heavy on off days. Maybe on your 3 day break you go
1. Squat / Bench / Deads
2. Off
3. Squat / Press / Dead or Light DL variant
Then on 2 day break its
1. Bench / Press / assistance for Chest/Delts/Tris
2. Squat / Deadlift / Assistance for Back
