What parts will I need.

Hi, at some point in the near future I may be able to put some nice shiny parts into a 2zz-ge engine, my main thing is with the pistons, I kind of want to splash out and get cosworth pistons, that will give me the options of 12 or 14:1 cr, I want 14:1 but wi that be too high for a road car?
Also someone said that I will also need to get the engine sleeved, is this a must or more a precaution?
Also with the valves and valve springs I have the choice of ferrera and supertech, I think supertech are single springs that are 53lb and ferera are dual springs and 72lb, considering I am hoping for about 9000-10,000 rpm (ambitiot but worth a shot) which would be more suitable.
Obviously these are not the only parts I will be getting but these are just the parts I need advice on.
Thanks for reading i will look forward to your replies

14:1 might give you detonation problems. You'll definitely be stuck with 99 RON fuel. Possibly higher, BP used to do a 102 RON Unleaded at something like £2 per litre. Ouch

Yeah I have read a little about that, is there any additives that are strong enough to make that much of a difference?
