What type of cam for Lifan V2 roller-cam head?

[Psomniferum]

Here is the new head I got for my Lifan 150cc. According to OMB warehouse, I should use THIS cam for my engine up to 150cc.

I should use THIS cam for OVER 150cc.

But TBParts lists these cams as their KLX-models. What gives?
Here is the smaller V1, again

And the larger V2,

I've worn Vince's patience out at TBParts with my 100x questions, haven't received a response from him for my last few questions. Does anyone know the answer here? I'm sure the cam Vince gave me will work. I'm just wondering if there is a selection out there, or are Lifan owners limited to this one cam? The cam he sent me reads "Honda/Import model" on the package. But TB has a SEPARATE cam for the Grom/Monkey engine. Is THIS cam for a Honda 110, then?
:hmm:

just going by what the pics look like, the second one you posted for over 150cc looks like it will have substantially more duration to the cam profile, aka, more loss of bottom end, but gains in the higher rpms. the sub 150cc cam appears to have less duration, which will shift the powerband lower, and retain what little torque a sub 150cc motor would have. just going by my eyeball of the pics...LOL
