No flycutting with stock heads will be necessary. As far as the 918 springs with this cam, I would ask the guys at thunder to be sure. Mine came with .602 exhaust lift and I plan on running PRC duals.

Ive always been a fan of beehive springs.. you should know that casey...
600 lift is a safe region... beehives dont have a single resonant frequency, they might be able to be pushed a TAD beyond max recomended lift.
