No , you have way more than 350 HP. each engine if running 77 on gps w/ 4 people,,more like 425-450 hp each, an HP. 500 is 485hp,,, FIVEPTOHH , is running 496'S, and you are same as him on speed, what is compression on each now compared to leak down., and what brand props are you running, reworking the heads will help, and maybe the props need worked also.
