          I'm fascinated with this project, even though I've never done anything even close to this! You must be planning a pretty aggressive cam!

          How well do valves like that cut? I've only seen ones with commercial cutting edges.

              High compression combined with cam and extra flow = awesomeness! Looking forward to results!

                I would hope forged aluminum is softer than stainless steel

                          I know why you cut the pistons, but what is with the valves being notched like that? I have never seen that before.

                          Edit: wait was that to cut the pistons by spinning the valves in an old head? I just realized the picture with them in a head was an old head.

                              Okay that makes sense. This build is very interesting also, curious to see what kind of numbers you end up with.
