One very knowledgeable person who posts here and who has done lot's of studies related to this is Jay Stukenholtz. Certainly one to listen to !
Not long ago I worked with Tim Goolsby at Bullet Racing Cams for a new solid roller cam in my current 505. We ended up with UltraDyne lobes and with 4 degrees additional exhaust duration and with a 110 lobe separation.
Tim worked with Harold at UltraDyne for 21 years.
