roller rocker ratio

Hi Guys
Finally got around to removing my camel humps,replacing them with some aluminium heads 64cc 210 runners,my cam is a 280 magnum 480 480 lift,would I benefit from replacing 1:5 rockers with some 1:6 rockers(resulting in a 510 510 lift)I was told the 210cc runners are too big for my setup?
+60 sbc,rpm intake,flat tops,600 holley.
Any imput would be great?

Totally up to you but unless you're racing around your streets at 6,000 rpm you'll never notice the difference.

Thanks for your replies,think I will run it down the strip see how it performs,hopefully runs quicker than the camel humps! May look at swapping the cam then,just bought some howards retro roller lifters for a future build! so i might use them with a good roller cam. always felt that the camels were holding back on the top end,or the 600 hollley. Thanks F-BIRD for your detailed advice!
