Just the bowls.

The latest version was about 10-20cfm better with with that same amount of rework.

Looking through some old notes......
on a set I did that had the freeze plugs on the end(first version), with the seats/bowls cut, but before any porting........with 2.19/1.88 valves...... 255/184@.700
Opening up and blending the bowls and rolling the short turns got you to 282/225@.700
Clean up the rest of the runner, trim the guide bosses, sand roll finish.......brought the numbers to 300/238@.700

Edit- I found some more numbers from when I did that set that had the freeze plugs in the ends.
