Trularin,

I am in the process of having a motor built, and the ARP stuff was supplied by a top engine builder here in the southeast that was the site of the dyno testing for Cracker's KC engine and builds everything from NASCAR to Powerboat race motors. I was amazed at the pains and special tools he uses when dealing with ARP grade studs and bolts to properly stretch them. It is by no means a process of taking a torque wrench to them and tightening them down. I found it most interesting and even my engine builder of many many years got an education. This is a science unto itself as evidenced by Carroll Smith's books.
