Has any one Polished & Ported their heads on 750 or 760? Any pros & cons?

I don't think it would produce any noticeable effects you would have to do a dyno run before and after, plus it would be quite expensive. Plus porting and polishing is just one step in the series of modifications in the intake and exhaust system to get the desired results
Modern ECU cars are torque / HP demand. You won't notice any difference in amount of Torque or HP without a tune to supplement it.
