I am porting a set of #5 heads, this is the first time I have attempted this. Can anyone post some pics of the bowl areas that have been worked over? I have the exhaust side done but I am concerned about cutting in to the water jackets on the intake side ( I don't know where they run). It looks like there is a lot of material that needs to be removed to make the sides below the valve drop straight down to the bowl area. Any tips or pics will be a great help to me. Thanks guys.
