I've been running a Cometic for a while. No problems. Mine is misted LIGHTLY with copper spray, the Cometic directions specifically say not to do that.

I used to have a KA-T but I only ran a half bar of boost, now it's N/A. But the head gasket has been fine for a long time. I have ARP head studs too.
