Well sounds like its running well whatever you have hidden away, Theres no need for verniers with the 135 cams, so you could have some fitted. Its still a very good result for a 120, My 120 had 52mm tb, VVC inlet mani, VVC exhaust mani, Decat, Janspeed cat back, open cone and that made around 125-127! So sounds like youve found a nice motor
