Training for a Bench Press Competition

[VaE39]

So I signed up for a bench press competition and we had the prelims today. They don't matter because everyone makes it to the finals anyways. The finals are in a month and I've been doing my regular Upper/Lower routine Mon Tues Thurs Fri. I'm trying to find a new way to get my max bench up. I want to keep doing upper/lower if possible. But right now my routine looks like this:

Monday: Upper
Flat BB Bench: 10,8,6,4
Incline DB Bench: 3x8
Single Arm DB Row: 3x8
Lat Pull downs: 3x8
Side Lateral Raises: 3x12

Tuesday: Lower
Squat: 5x5
SLDL:3x8
Calf Raise: 4x12
DB Lunges: 3x10
Decline Sit ups: 4x12

Thursday: Upper
Bent Over Row: 10,8,6,4
Pull ups: 3x10
Incline BB Bench: 3x8
Flat DB Bench: 3x8
Rear lateral Raise: 4x12

Friday: Lower
Deadlift : 4x5
Squat (light): 3x8
Hack Squats: 3x8
Calf Raise: 3x15
Leg Lifts: 4x12


I was thinking of changing my Upper Thursday portion to this:
Flat BB Bench (heavy): 4x5
Military BB Press: 3x8
Bent Over Row: 10,8,6,4
Pull ups: 3x10
Rear lateral Raise: 4x12

Any thoughts or anyone with experience in Bench Competitions? Right now I'm 145lbs and I've maxed at 265lbs. Honestly, when I did 265 it wouldn't have passed the rules for the bench competition. So I'm trying to be more strict with it especially on Thursdays when I go heavy.
