455 Bar Size?

[ebUpstateNY]

Hi All, thanks for the add.
Been running the Rancher for 20 years or so, cleaning my woods and splitting firewood. I now have some 24” oak and hickory and have a couple questions…
Can I mount a 20” bar?
Will the size make a difference or is it more a power deficiency?
Are there more aggressive pro chains available in 20” than the prosumer selection at 18?

Thanks.
