Both riders are poised on 13 victories apiece on the big bikes, although that could change on Saturday, when McGuinness starts a a red-hot favourite to follow up his Superbike TT success on the Honda Legends Fireblade.
In the Lightweight Supertwin event, Ryan Farquhar is fancied to build on his North West 200 triumph in the class.
MotoGP rider Cal Crutchlow and Moto2 ace Bradley Smith will complete a lap of the circuit in the Monster Energy Parade Lap prior to the Saturday Senior race.
