I have being thinking about this process instead of the usual port, port match etc. I reckon its a good idea for the exhaust side of things but im lead to believe that a slightly roughed up intake is good for the combustion process and mixing of fuel/air.
I also hear its the same for the valves-rough intake, polished/swirled for exhaust. I have no idea of places near me who do it either which sucks. I need to look into that
What sort of prices have u been getting up your way Joel?
