You could probably squeeze another 20hp out of your stock 5.5mm elements by tweaking the pump. A pump adjustment would delay the end of injection to increase fuel quantity. This will result in higher egt's, partly because more power is being made, but also because delaying the end of injection can allow the combustion process to continue after the piston has moved too far down in the bore to efficiently make power. A bigger element can deliver more fuel in less duration, keeping EGT's cool. You can get 8mm elements adjusted for just a 20hp increase too, but the engine will be louder and driveability will suffer compared to the 6mm elements.
You should contact dieselmeken. He'll tell you what pump mods you need to meet your goals and you should search some of the big element threads here to brush up on your diesel theory.
EGR is supposed to reduce oxides of nitrogen by reducing combustion chamber temps with inert exhaust gasses. All modern diesel EGR systems have an EGR cooler now so the effectiveness of the uncooled EGR system on the 603 is dubious.
