LA small block,Do you put an oil passage in your head stud?

From ARP.
"The modulus of elasticity of all alloy steels is exactly the same – 30,000,000 psi. This is true whether it is heat-treated or not – whether it is 100,000 psi strength level or 300,000 psi. Metals are like a spring – put a load on them and they will stretch – double the load and they will stretch double. This is important in connecting rod bolts because by measuring the stretch we really are measuring the load. Load is what is important and measuring stretch of a given size and configuration bolt will indicate how much load is stretching the bolt."

Listen Mr. scientific engineer with the 300 million PSI Heat treated double stretch alloy spring steel bolts. These are not rod bolts. They are head studs. He has a stretch gauge for rod bolts. How would you measure the stretch on a head stud. You cannot. But a man of your expertise would know that

Stretch bolts for heads you toss and get new bolts everytime. Studs are usually used Many times unless you over torque them and ruin them When slamming a valve up through the head with a piston.

When he would pull the heads off the Nitro engines He used them over and over and then over again until the block is resleeved . Then they come out. If they look good on a thread pitch gauge and they go right back in. As long as they torque to spec. They are special cut and are to dam expensive to throw away .

I am sure you saw the thread I just posted with parts for my engine, There is tons of money in my engine and I am tearing it down to go bigger and better with all new parts . And guess what Steve is using over for the 4th time Those studs.

So you know what I think of your metallurgy lecture the The "modulus of elasticity" Pull the elastic on your underwear and let it fly.
