ISX DOHC Needs new head.

[Scottj96]

I have an 07 kw w900 with the DOHC ISX and we have determined that the head is cracked as I am getting fuel in the oil. I see aftermarket heads and oem heads. I can get an aftermarket {garbage head} for $3500 or I can get an oem for like $8000. I don’t really want to put a head that I know will eventually crack back on but I don’t want to put junk on either. Looking for pros and cons of both please
