Head skim & Gas flow

[Anonymous]

Where can i get a 1.3 sr's head skimmed and flowed? do i just approach a local engineering firm? or do i need to go to a proper performance tuners? can the flow and skim be done without taking the engine out? (sorry if that sounds stupid, but i had to ask!!) how much extra power would it give me?

I desperately need advice...cos ive asked about 3 times b 4!!!!

cheers guys

plus, is there different amounts of head skimming and flowing that can be carried out? if there are could anyone tell me what to ask 4 when i take it to be done? (i want a good performance increase but dont want to affect the cars reliability)

cheers
