Need Help with Evo 9 Cams

So i plan on buying cams for my evo 9. Its a stock block with fp black, bolt on, and a 450 pump. Was wondering if i can run cams without upgrading my valves and springs. Any suggestion on what cams i shoud get. trying to hit 450HP.

Run those S2's! (many of us do!) Must get the springs for sure! I would get the Ti retainers as well!

No need for any valve work.

S2's and the appropriate spring/retainer is kit is a good choice, the GSC 5040 part number.

Are you trying make 450whp on pump gas or E85?

Based on limited info, You need bigger injectors and e85. Then 450 will be cake, even without cams. On pump gas, a mild cam will help. Maybe something not requiring springs. Hopefully someone can come in. Also, you would swap springs and maybe retainers. No need to change valves.
