There is no halachic requirement or source to have long peyos besides the ones on the sideburns. It’s nice of course and goes into the Category of hiddur Mitzva.
Regarding how to wear your extra hidur Mitzva peyos, each should follow his customs.
FYI the first ones by far to have the long peyos in front , curled or non curled were the Yemenite Jews. That’s where todays chasidim got it from
