Need some help archiving my goals

Hey guys my current 3 goals are 1. a 3 plate bench, 2. a 5 plate deadlift, 3. 16inch arms. Any advice on training would be appreciated I’ve always struggled building my arms. Currently I have a 275lb bench, 14.5 inch arms and a 425lb deadlift. My plan is to not stop bulking till I achieve all 3. But any tips to further increase the speed I get there? Thanks all.
