Porting, What do you guys think?

I would say do it, since I had experience with a half bridge port, though it was a S4 13B.

I'm not experienced with tuning with carbs, but I think it would be pretty easy.
I tuned mine with the stock S5 NA ECU, throttle body and CAS.

If you go for it,
Be prepared for noise, bad gas mileage, and some light throttle hiccups.

Also be prepared for noise, on command flame shooting, and a fast revving engine that kicks like a mule up top.

And if you think you'll lose low end power, just step on the gas.

shouldn't i retain stock low end with the stock primary port, will the 465 cfm be enough? will timing be difficult seeing as the stock low end and highly modified top end?
