Hi
have a read here
http://www.v8forum.co.uk/forum/viewtopic.php?t=9749
not sure what you will gain height wise if that is your aim but plenum roof height to inlet tract end is a dimension that effects the shape of the torque curve (but not much on an engine with power output of the rover). Quite honestly compared to the addition of the turbo anything else is just painting the wheels.
best regards

Its a common modification to lose the trunpets and blend the base. Moves the power up the range apparently.
My TVR currently has this set up and produces nice torque and 308 bhp.
I wouldnt worry too much about losing trumpets, especially on a boosted motor.
