You'd have to compare it to your OEM to be sure.
I used an S3 race ported cylinder on a 2010. The porting was nothing out there. Mostly the exhaust port had just been moved up a bit to favour top end peak power. Obviously all the ports were nicely dressed with no casting flaws evident.
You may find using a thinner base gasket with the S3 will keep similar port timings.
