I fun the ARP 10 stud and nut kit in mine and have done for 12 months now. I'm running stage 3 and quite a bit of Nos and have never had any trouble at all.

Not using a cometic either. I wire rang the block and fitted a standard head gasket fo a tenner

As for fitting them. I loctited them into the block and then applied there lube to the nuts and washers and torqued them all down to 90 ft/lb just for good measure
