combustion chamber polishing

picture of combustion area before porting


cylinder head was skimmed up to 2 micron only..just enough to get the mating surface flat and level..job done by using the stone grainding bit and not high speed steel or carbite or wat so ever..



clean is first priority...huhx.. 4 5 kali basuh chemical whooo..2 3 kali basuh ngan minyak tanah..

nice...
