I would remove the 5 & 6 port sleeves entirely, and use some JB weld or similar to build a "ramp" for the air entering the ports, so it's not such a right angle turn entering the chamber. (Like these, but in the port itself instead of the sleeve: http://www.pineappleracing.com/6-por...sertspair.aspx)

I've done this to very good effect on a similar hybrid motor, a GSL-SE 6 port with S5 NA rotors & weights.
