ok, i think reliability also could be improved by fine-selecting your cam, i read before that you must choose a high duration cam not a high lift one(relatively), because high lift cams put more stress into the valvetrain wich will decrease the overall life of the engine, for example scat c-35 has .410" Lift & 286 Degree Duration, Engle w-110 has .430"Lift & 284 Degrees Duration, they both have close duration, but engle has a higher lift, that means is make more strees on the valvtrain. also the lope shape decides that, sharp lopes is faster to push, so it is also not good for the engine...
i'm not sure about informations about valvetrain stress, as i only read it but not experienced it yet in the real world, so if any one knows better please correct me...
