intake selection for 600hp 451 ci

So I put my motor together and am about to dyno it trying to hit the 575-600hp mark, its about time to dyno but am second guessing my intake I currently have a ported tourqer and am thinking about going to a victor.
motor set up is
451 400
10.8:1 compression
Cnc edelbrock that flow 320 @ 600
Hughes .588/.600 .250/.254 @.050solid cam
2"tti headers
850 hp carb
1.5 rockers

Am I on track for 600hp? I'd rather swap out intake or save the 300$ and install 1.6 rockers now if needed befor it's dyno time. I know my duration should be alittle more but It fit my turbo action convertor and didn't plan on going this wild
Any help would be awesome!
