I would think if anyone had done this it would be somewhere in the AO Archive, not here. AGD went to the round hole style for flow, exactly how much over the original I have no idea but TK wouldn't have made the new part, which is more machining operations thus more expensive over the old unless it was worth it.
Aftermarket ones are reported as hit or miss - like the Reactor. Some see improvement, others see nothing.

Yeah I joined over there, it isn't the best layout. Most of the recent threads are asking for donations to keep the site alive. Kind of irritating. Rather than AGD or Tom taking action, they are asking for handouts.
