Templates only show you what size to open them up to. A template can't show how to do the real work that actually makes the most difference. It is possible to make a port larger and have it flow worse.



You will need a die grinder with some fairly expensive bits to do a nice cut. These generally aren't available at the hardware store. I've got some nice carbids and non ferrous bits that I use for various things. I only use a Dremel to go back and do finish work. It is possible to port an engine with only a dremel but it is also possible to cross the Atlantic in a rowboat. It's slow and difficult.

Nice analogy.

It is easy to port a motor, its not easy to make the ports make power.
