steering head

If the handlebars are out of kilter due to the frame being bent and not the yokes then the front wheel (and yokes and Stanchions) will not be vertical. Put the bike up on the centre stand on a solid flat area with a helper on the bike hands on the handlebars. Lie down in front of the bike and ask the helper to move the front wheel slowly from side to side getting them to stop when it looks straight ahead and gauge if the front wheel is vertical. Also note the yokes and stanchions for how they look. Double check the handle bars before, even new ones could be bent.
