Cams for a big bore kit

I'm building a motor with a +3mm crank ,98mm hi-comp piston ,ported and polished head and not sure which full exhaust but prob DASA and I'm looking into changing the cams...heard something about using yz450 intake cam and doing the mod with the stock exhaust cam? Or what aftermarket cam should be good?

I'm guessing this is an EFI quad not a carb model?

Definitely do the cam mod on the exhaust cam but I do not know on best performance cams. I think someone told me Webb cams but not sure.
