Porting them later is a solid and easy option that will only compliment the cam more.

I don't see the variables...you're basically increasing the airflow either through the heads and intake (since If I go L92, I have to go L76 mani) or through a cam through the stock Lq9 heads.
I guess one variable would be the spec of the cam. Let's say an aggressive FI cam that's streetable. It won't ever see the track as it will be a weekend cruiser.
Thanks
