Thruxton 1200s Fitting 2021 Speed Twin Engine

Have 2016 Thruxton 1200s done few miles 55k but have acquired 2021 low milage 5k Speed Twin engine in near new cosmetic condition complete with throttle body and injectors . Not sure if its later higher power engine but think it maybe as it has a breather on cam cover like on later engine (mine has no breather on cam cover ) . Any idea of any problems with engine swap , was going to use Speed Twin throttle body /injectors as same part numbers on all 1200 twins HAH9840 engine number " if anyone can tell what engine I have ?
