Combo 13.
Combo 13 is close to Combo 12, but it uses the 190cc Street heads instead of the 195cc version. These heads are supposed to be better suited to the smaller 350 cu. in. small block. Notice that the 270° Magnum is very close to the cam in Combo 12. Perhaps the reason for the power and torque increase is the larger 750 cfm double pumper and extra half-point of compression.
