I don't know if the 39mm ports are too big, but I do know that the 34mm ports are not too small.

I got 200RWHP on a 3.0SC with 34mm ports, 20/21 cams, and 40mm PMO carbs with SSI's.

Since then I've advanced the timing, and played with the jetting, and the car definitely feels faster, but I've not had time to get it onto the dyno again yet...
