I had this exact thing done to mine when I sent my heads out, but I don't want to advertise for an other vendor in EQ's thread, so I wont say where here. For all I know EQ can do this as well.
all that needs to be done is the side widened a little and then blended back into the chamber, plus a little deshouding behind the valves doesn't hurt. My combustion chamber final size was on 51cc so I didn't loose much in my compression ratio either.
