Re: ARP Head Studs, TQ Settings? MelloYellow, all studs go into block hand tight so threads have max. perch contact for strength. Next most manufact. reccomend 75%torque of studs yield strength. I dont know its yield strength but either ARE or ARP can tell you that.BTW if you dont mind pulling motor to remove heads, studs are the only way to go! <img src="gr_grin.gif" border="0">
Re: ARP Head Studs, TQ Settings? When talking to Nick at ARE he told me in a F-body if you make some minor clearencing, you can get the heads off the car with the motor still in the car. I don't know what exactly you have to do but I will find out sometime soon. I am going with studs also to try and keep the heads on the car with a 300 shot <img src="graemlins/gr_devil.gif" border="0" alt="[devil]" />
Re: ARP Head Studs, TQ Settings? ya, I kinda figured you could do that also. I know it's still not going to be as easy as with just bolts. But you gotta have something there if you wanna run high boost or lots of nitrous.

Re: ARP Head Studs, TQ Settings? Another real good reason to use studs is threads in block over time can pull from being aluminum. This is a real problem with Cadillac Northstar engines, and over time may really start to show up with LS1. Just a heads up people <img src="gr_stretch.gif" border="0">

Re: ARP Head Studs, TQ Settings? I believe my gaskets have something similar to an O-Ring inside them. Looks like the stud specs come printed on the back of the ARP box and inside is a sheet with the PSI Tensile & Size. 190k PSI Tensile and 7/16" studs I believe. TQ Specs are on the back and vary per 30W or Moly lube or something. It's all there.
Re: ARP Head Studs, TQ Settings? My car has ARP head studs since after 6 head swaps, the threads were getting very tired. MTI torqued them down, so I do not know what the torque should be. But I have made sure that you can still change the heads with the engine in the car. You have to remove the plastic piece under the cowl, and then supposedly, the heads have anough room to slide off.

Re: ARP Head Studs, TQ Settings? So is it possible with the motor in the car to place on the head, and then screw in the necessary studs with your fingers? I know the bolts inside the head area are in a tight space. I wouldn't want to get these expensive animals and then not be able to place the heads and then the studs on in the block.
