summit cam selection

Found some info in archives, but wanted a little more info...

Have a bone stock 318 with a performer 4 bbl intake, 600 cfm eddy, stock exhaust manifolds from a 273, dual exhaust.

Engine is going in a 65 valiant with a 4sp and 3.0x gears. Would like to replace the cam with something a little more than stock but not sure which summit cam I should use. 100% cruiser

K6900 : 204/214 duration at 0.050, 420/442 lift
K6901 : 218/228 duration at 0.050, 441/441 lift

Leaning towards the K6900 - what do you think?
