I know some good knowledge on flow and modding of L36/L26 parts have come out of here in the past.
If someone removes the intake runners in a L36/L26 and puts in a ZZP HV3, has anyone seen improvement by removing the ribs in the top of the UIM (that helped hold old runners and possibly guide air flow)?
