Ya know anybody running one on a cummins?

 

Actually i have a friend who is running one. Hes running 14mm studs and o-rings. They never have been able to get the gasket to seal up completely, theres always just a little bit of seepage between the head and the block, but from what i understand thats just a characteristic of a copper head gasket. Right now theyre running an Aurora5000, a set of big sticks, haisley cam, and an 800cc scheid pump. On the last pull of the year they lifted the head and it spewed coolant everywhere, but theyre hoping to fix that with a little crank case ventilation. I took a look at theres before they put it on the truck, its pretty much just a solid piece of copper so i really dont see any way the gasket could fail unless you could manage to blow a chunk of copper out of it.
