I'd be careful with port size. I got Andrew to go to the maximum of the Renault gasket. I'd decided to go for the standard port size as I wasn't planning massive power and I'd prefer to keep the gas speed and torque higher.
If you planning over 230-240bhp or so then maybe a step up to 197/200 inlet port size would start to benefit.
