How much torque on ARP 12pt studs?

I have a built 346 w/ARP 12pt studs. I'm running 317's with GMMLS head gaskets. My compressin is at 8.9 and I'm going to be runnig 13lbs street and 17lbs race. What would be the desired torque for my setup. I recently blew a head gasket at 14lbs. I had the bolts torqued to 75#. Any help would be appreciated.

Thanks,
John

Thanks bro. 75#'s is where I had them torqued before with the ARP lube. I wasn't sure if 75# was enough.

you just get them to bottom out and then back off just a TICK...like BARELY. Not that critical as long as its not bottomed out

Ur head gasket certainly didnt pop cause of the torque u haed ur head bolts at. they only pop when u have a tuning issue or u had a random problem at 1 time. GL man
