Help with Rotom heat Ev spread

Question

Is there a possible way Rotom heats HP,Def,and SpDef stats goes more than 300 with a bold nature?
I want its HP,Def,SpDef to go over at least 300 at the same time.(No cheat)

Answer 1

Sadly, that's impossible.

But with this EV spread: EVs: 252 HP / 96 Def / 160 SDef

He will get 304/301/290 bulk spread with Bold nature.

That's about the best you can get.
