The gun's range an accuracy comes from the tightness of the air seal, the hop-up chamber and rubber, and the consistency of the inner barrel. I've seen well tuned 250 FPS guns out preform china-clone 400 FPS guns.
Alot of high end aftermarket cylinder heads will not work because the Cyma gearbox has an extra bit of reinforcement in the front of the mechbox that the TM one doesn't have, so the cylinder head has more material than there is room for inside the Cyma box.
If you do get the aftermath one, I'd recommend sending it off to a gun tech to get cleaned, properly greased and get the gears shimmed correctly.
If you do get something you didn't pay for, give Cabelas a call, I'm sure they have some sort of Customer Support. (I find it's easier to call them and speak with some one instead of relaying Emails back and forth.)
Hope this has been helpful, if you've got any more questions, feel free to ask
