honestly i wouldnt use a dremal tool ive seen what a head done with that even by a talented person looks like. I spent $400 on tools made just for doing head work. I worked at a machine shop for a while and thats where i learned to do it. If your trying to get mechanically inclined i wouldnt start with something this advanced. I wouldnt attempt something like this until your good at like disassembaling a motor and reassembaling it and it actually runs right when finished.
