Bleed for sure. Get someone to look under bonnet will you push clutch to see if slave is pushing clutch lever. If air in line you will see it only move a fraction until you get rid of the air it starts moving more and more.
Clutch will also take up at different spot now so you may need to adjust master cylinder piston length near the pedal box. This is a must anyway whenever you replace clutch. Just undo locknut and rotate shaft from master cylinder to clutch pedal.
New clutch will be thicker so should contact earlier so you should probably have to lengthen the distance..can't think at moment but sure you can figure it out.
