While I really enjoy the "rhythm" of the timing you currently have the stamps set at, in reality they would have been more evenly spaced around each revolution so as to evenly load the power source driving them. Unless I'm not seeing correctly, it does look like you have all four stamps being lifted at the same time, although not at the same level of lift.
thanks Daniel , I had them set for 2 up @ 2 down at 1st , it is possible set these up
For anything you desire as they are infinitely adjustable.
