I would say it is as reliable as to how well it is built. If you build it to thier specs and follow thier recomendations and you do the proper maintaince it would be good. I don't think they would sell a kit that makes the motor a hand granade. But if you just slap the stuff together and don't follow thier recommendations it would probably be like shooting yourself in the foot. I have not used the powroll kit and this is just my .02$ worth.

I've got that powroll big bore kit. I've had it for a while now and haven't had a single problem. It cost me $400 after the machine shop bill. $400 won't buy you a 400ex. As long as you make sure to put the engine together right, torque bolts to the right settings, adjust your valves, retorque your head bolts after you break in the engine and run good oil(not the cheap stuff) in it you should be fine.
