As I know they are the same
But Riva will include Rocker shaft bolt with it
And the Rude will include valve seal
I prefer Riva just my .02 cuz it will save almost 35$ for new rocker shaft bolts that Must change when upgrade valve train kit

Thanks for the answer, and what about valve seals? I heard that it's impossible to reuse them, when changing springs and retainers.

Valves seal are away from your work
Your work is just remove the OE spring valve and add the upgrade valve you don't need to touch the seals unless if you want to change them
I prefer this tool from Riva it make it very easy job no need to pull the engine head or even pay more $$$$ for engine head gasket
How many hours on your ski?

Maybe Nils will chime in but I think there is a reason for the new seals.
I think it gives more clearance for high lift cams if I remember correctly??
I think they are shorter than the stock ones?
