Question What Intake Seems To Flow The Best On 454mag?

I'm thinking of changing my intake and wondering what works the best on 454 mag has victor jr on it now was told the new dart oval ports pretty good.

also wondering if I dare raise the rpm a little higher spinning it 4900 now was told that a mag could go 5200 this is not a new motor but it has upgrades like headers and intake stock carb.

want more speed$$$$$$$

Just keep it under 6000 rpm. I run my 502 mag at 5400 rpm. with the 23 mirage three blade I was running at 5800 for about 2 months. Stay in your power band. The higher the rpm the shorter the engine life.
