The best info on hemispherical heads I found was for race bikes.
As the squish area goes all the way around in a hemi it is not clear how you would do it.
I guess you could add some even spaced all the way around.
but I would see if any of the bikes have done it. I think if the squish is working on the hemi that is as good as it gets. but I think the squish is not effictive many times do to too much clearance.
for it to work right it needs to be very tight almost touching at redline.
who here has even meshered the squish ring? let alone changed it so it is tight all the way around.
