rods? for my 347????

[88stangmangt]

i just bought a set of H-beam rods for the 347 stroker i just decided to build LOL are the h-beams(4340 Forged Steel H-Beam) to much? the standard ones say they take up to 475 hp but i would like it to do more that that if i decide to turbo it so are the forged h-beams overkill? or should i just get the standard 5140 Forged Steel CNC Machined Beam rods? (both 5.315)

THANKS GUYS!!!!!!!!!!!!
