Ok I bought GSR arp head studs and I'm a little confused. The back of the blue box said torque them to 63 ft lbs with the provided lube. Inside the box on a sheet it said torque them to 80 ft lbs with the lube. Factory of course is 63 ft lbs. (if there was a cross eyed smiley it would be here)

I will of course be calling them tomorrow but your feed back would be appreciated.

 

just do several passes up to 80ft lbs. they are arp, meant to hold that head on.

 

eeesh, in for answers

 

deffinitelly find out a for sure answer before just doing it.

 

Ok I spoke to an ARP representative. He said that the specs on the back of the box are just general guide lines and that I should follow the sheet included in the box. He double checked his facts and assured me that the should be tightened to 80 ft-lbs with arp moly lube.

Of course they are to be done in order as specified by OEM in three steps (aka all torqued first to 26 ft-lbs in order then to 52 ft-lbs and finaly to 80). That it to be done 3-5 times. So all said you could have 15 steps at the most.

So if your ready for your arm to be tired just thinking about it thats 10 nuts with 3 steps and 5 cycles = 150 times you'll be torquin those damn things up and thats excluding the OEM untorquing sequence (which is in a different order 1/3rd a turn at a time until loose)

It could take me two days to just put the head studs in!!!!

 

damn that sucks well at least you figured out how much you have to torque them now. gl
