There is a difference between a Rushmore stage 1 and a pre Rushmore 103. The tq being higher after 2014 is the ho cams vs the pre 2014 stock cams. So a 2014 up will have more power. The op running more compression gives the extra tq along with the higher lift cam. The springs are at the cusp of .580-.600 the beehive can handle. I wouldn't have went that much cam without the headwork to support it. So the 120tq is more than just cams added. Had some headwork been done the HP would be higher.

The heavy valve springs are unneeded and may cause more wear and stress than by doing good. Also may hold back the build without headwork to support them. Overall not bad but you really only have what cams usually will deliver for power and add a couple ft lbs tq for the compression compared to stock. Not raining on parade but a 107 would have been likely cheaper and better performance. Just cams,good pipe and air cleaner on my 103 dyna was 93/107 sae. Either way enjoy the ride.

Yeah my dealer said "it looks like it would probably work with the stock springs but Harley suggests the other ones for a reason"
