Has anyone ported their head? How were the gains?Or is there an aftermarket one you can buy that flows better?

No one on GenVibe or MO has ported their cylinder head.You could possibly see gains of 15-20 hp.There are no aftermarket cylinder heads available.A proper port & polish with a 3 way valve job + increasing the valve diameter 1-2mm would run around $1000-1500 at a reputable shop.You would also need to get a custom intake manifold and branded header, downpipe & midpipe to take full advantage of it. (probably another $750.)Not really worth it for what you get out of it. I had done research on this last year.
