Before I put my shelby valve cover on should I re-torque the head studs? I have a cometic gasket and arp head studs. I have about 1800 miles since I put the head on and I have never re-torqued them. What should I torque them to and how should I do it? I plan on running 27 psi this year.

I just run the torque wrench around at the max torque I torqued them too originally. With a cometic gasket it may not do any good but it only takes 5 minutes to make sure they're still holding torque.
^ what he said... it can't hurt!

since head studs are not TTY, and you are soposed to retorque them after a heat cycle or 2.....i think a retorque couldn't hurt

Your not supposed to but if you want to, knock yourself out. I have never done it and haven't had a head gasket failure, even at 30+ lbs off boost.

I think the age old debate was for age old head gasket technology.

I did the last time I had the valve cover off. It cannot hurt to do it.
I just put the torque wrench on them and they were all just below 90. So I just set it to 90 and they just moved a hair.

sounds fine to me. i retorqued mine after a few heat cycles (arps) and I am running the MP gasket. its been fine for a few years.

1st time I put in studs with an MP gasket I didn't re-torque since it was about a 50/50 split on doing it and not doing it on the old list's. Well the next morning after checking I had no leaks I went out on the freeway and got on it. The head lifted and sprayed coolant all over my airbox. Been retorquing them ever since and never had another problem again.
I had a Cometic bolted down with ARP studs on the Z, retorqued after the first heat cycle, only torqued to 80ft-lb, held to 30psi no problem till the rod let go...
