If your not after all out HP and would prefer more bottom end and torque for tighter tracks which would be the way to go. Going to get one for sure but not both. Not ATM anyway

well from personal experience i can say the v2 head is SOOO nice and wakes that motor up like you wouldn't believe. the 165 bbk will do a little but mainly just add more bottom end i believe. the head adds everywhere and makes it very fun to ride
160/165 kit makes 178cc on a YX160. If you're up to splitting the cases to open them up for the bigger sleeve, and get the KLX kit that doesn't have the turned spigot, a 65.5mm Akunar bored in to the kit jug gives 192cc of torque monster. Do a little searching for feedback on this combo, there's a few out there and they're monsters
