ANY porting you do on the 6 port block will reduce low end torque. The 6 port blocks already have HUGE ports.
Limit your porting to the primary ports by moving them up a little. Don't move them out towards the rotor housing.
Move the exhaust ports up a few MM and widen them a few MM. Remove the diffuser.
Move the aux port out towards the rotor housing a little.
A good port template is the Mazdatrix 6 port template.
