Oh god yeah, but it's meant to be like that, if they'd made it any better it'd have competed with the XSi too much!
They're 115hp, an XSi is 130 - they're literally a raw casting of an XSi head from what I can see, just none of the porting done to the XSi head to make it better - the GTi6 head is significantly better - it has spray bars, double valve springs blah blah, the list goes on.
