Is this for a .21 size?
CMB made different Green and Red Head,
you have the .21 CMB RS red head (rear exhaust),
CMB Valvola RS-7 (front exhaust),
CMB Valvola Green head (front exhaust),
CMB LS Green head (rear exhaust).
All of CMB's engines are great engines, I don't think you can go wrong with any of them, the Valvola Green and red head both delivers their max HP at a higher RPM than the RS.
Dan.
all in all, which ever you choose is a good decision.
MAC and NovaRossi's are also great choices.
