Um, have you looked around at parts for the F22? Gude sells a reground cam. Nobody sells any kind of stiffened valve spring for the F22. There's no such thing as a titanium valve spring at least on the mass market, for any motor. And titanium retainers for the F22, forget it.
How much you looking to spend? I'm a similarly broke student and plans generally seem to take longer and longer to amass funding for.
Ferrea sells valves and springs as well as retainers for F22 engines.
