[TR] anyone have experience using APR head bolts

[Wbeech@flash.net]

I back off just enough to move the nut, they sometimes stick, then on to the determined setting.  I don’t re-lube, others may.

When re-torquing ARP head studs, do you need to back off the nut and lube the nut and washer before you re-tighten ?.

I did not re-torque my ARP’s after a TR4A rebuild and 2 years later blew a head gasket with no evidence of burn thru. Studs were loose and nuts came off much to easily. My fault as I always intended to do a re-torque but didn’t.

Have used APR on my last 3 TR3 rebuilds, never a problem.  Never heard anything about not having to re-torque.   I do after 2-3 heat cycles then again at 200 mile with the first oil change.

I used ARP head bolts on my last Stag. I torqued down the head, but never in the last 5 or so years did I re-torque the heads. I recall speaking to a technician over at APR and he said no need to re-torque  I have not run into an issue. But am wondering what other's have to say.
