No. Just no.
Why so much intensity if you want to train high volume + high frequency? I’m all for training a lot if you want to progress, but this seems stupid. How can you max on bench the day after heavy OHP?
If you want to OHP more than bench, try benching once a week at around 75-85% of max (or lighter) and focus on the OHP with 2-4 sessions (I would try 3 to start, and train bench after OHP on one of the days).
If you want to keep the maximal work, have one max day (1-4RM) and base the other two days on a percentage of that as you have done with the 10x3 day. One could be 10x3 @ 80% of your week’s max (or more if it’s a rep max), and the other could be something like 6x6 @ 70%.
A diet between 5000 and 8000 kcal is obviously not planned - try setting a goal and adjusting as needed, you don’t want to limit your progress by undereating.
Remember, OHP strength takes time to build, a 300lb+ press is not that common. Plan to spend years working, and don’t expect progress to be linear.
Good luck - a strong overhead press or push press is very impressive, so keep lifting like a bear! (Or maybe Zydrunas Savickas, but same thing really)
