Has anyone had issues with ZZP MLS headgaskets? I replaced it and everything went together smooth besides the stupid ARP studs hitting the headers. I am getting exhaust fumes/carbon in my coolant shortly after putting it on. I poured a bottle of Blue Devil in and it helped but took out a new water pump. (I hate using crap like that) I just put the car in my garage until I figure out what I want to do.
