having a little issue...

I do the same trick on the cam as Charrlie. I use my Dremel tool with the reinforced cut-off wheel. I have also done the rear cam journal (cam its self) and that has worked well. I also camfor all the oil holes in the block head and crank. I also cut the head where the oil wont run out where the stands meet the gasket area. I do all this BEFORE it goes to the machine shop.
