I hung around 400 for years as i was lifting in a shirt that time. I started to lift for my raw for a few months and put about 20 or 30 lbs on it with a comp pause. I can tell you westside did not work at all. the best thing i did for it was a program i got from a Canadian national thrower. it was basically you start low and do 8 singles that either have to stay at the same weight or increase so my first workout was this 345, 345, 345, 345, 350, 350, 350, 350. Then next week you have to start where you left off, so it was 350. After your 8 singles you do 5x5 at 80% of your last rep. I did these touch and go and the singles paused. I am 6'3 with long arms. My problem is i keep tweaking my pec at the bottom. I was lifting flat footed, but am going back to arching with tucked feet to see if i can take some strain of my pec.
I did that workout for 8 weeks or so and it worked well, i think my last workout i hit 8 singles at 385, 390, 390, 395, 395, 400, 405, 410 and they were all pretty good. thery were all paused.
Accessory work that always helped was pin presses of a few inches off my chest bottom up for sets of 5-8.
