I know where you are coming from but he needs to skim his head because he has a compression leak not caused by a broken head gasket but the head itself
The way I look at it, take it to a specialist and get the minimum amount taken off to allow the head to seal perfectly again. If you start trying to raise compression to make power, then pay for cams, valves, springs etc and at that stage you may aswell replace stem seals, valve guides, cam seals....the list goes on and you would be better spending your money on a type r motor instead
I paid £80 to have my head skimmed, pressure tested and de-choked then simply put it straight back onto the car and it is a very good going b16a. I'm keeping it like that for as long as it takes the abuse I give it on the track, if anything fails on the motor that isn't cost effective to fix then its time for a type r motor
