Dave, sounds like you have 2.4 T heads from an ROW engine. The U.S. Mechanically injected 2.4T motors had the 29mm intake ports. My guess is that they needed to detune the MFI T motors for a lower, fuller torque curve and to better match the T cams. The ROW cars had carbs, and 27mm venturis to choke them down, so they had the 32mm ports like the E.

But even if you had the 29mm ports, it is actually really easy to open them up to 32mm yourself. It takes a little skill, but all you are doing is removing a bottleneck, so it's not like a real port job. The bottleneck only goes in an inch or so, and all that is needed is to port match with the intake gaskets that have a 32mm opening. I used a socket that had a 32mm O.D. to help guide me in finding any high spots and to help keep the port round. Any bigger than 32mm, and you'd really need to know what you're doing, since the porting would need to go deeper into the head.
