i like the power band of a non vanos m50, it has that on the cam surge at 3500 or so, theres not as many cam choices for the non vanos but i think the stock cams are already hotter on the non vanos, it also has double springs, but the stems of the valves are bigger and take up more space in the port, no knock sensors, it has plenty of compression. i do think theres around 20 hp hiding in those cam gears in terms of cam timing, you just need to figure out how to measure your adjustments to track progress or failure. think of it like this, the non vanos and vanos make the same hp stock, theres some hotter parts in the non vanos motor, they detuned the tu to make it more civilized then made it up with vanos and electronics (imho)
