Default Head Studs vs. Head bolts

whats the difference between head studs and head bolts?

I have head bolts now on my H/C/I lt1. I will be putting my new 383 in my car in a few weeks and need to know if i need head studs? i will be using stock cast LE heads and be running about 15lbs of boost.

does anyone know the P/N on LT1 studs?

If running boost why not run studs... they're cheap insurance for your head gaskets. What CR are you going to be running. IF running a relatively high CR def get studs.

Oh studs allow a more precise torque measurement for the head, and also stretch less.

This may be a stupid question but, can you remove the studs without removing the heads?

The reason I ask I wouldn't want to have to pull the motor to change head gaskets. I know there is no way we would have clearance to pull the heads with studs in place!

I'd pull the motor anyway. It's a pain pulling the heads while it's in there

studs are definatly a good choice for you..........heres the deal on studs vs. bolts......

first off its easier for a race engine builder to build a motor with studs than bolts.....its just pain out faster to assemble........but more importantly, when you torque a bolt down its encountering two forces a rotational stress from torquing the bolt tight and a vertical axis sretch from the bolt being pulled apart......the roatational stress can skew the proper torque reading.....when we use a stud....the bolt is encountering only a vertical axis stress there fore alowing the bolt to be torqed down more properly and therefore prevents any lifting and shifting of the cyl head better than a bolt........

to install its simple.......first off use some kind of sealant on the threads that go into the block....all of our bolts go into the water jacket....put a small dab of black silicone on the threads that go into the block and thread them in HAND TIGHT...DO NOT OVER TIGHTEN THEM INTO THE BLOCK!! next pop ur heads and gaskets on and then tighten them down in the proper sequence and be SURE to use the ARP Ultra Torq Lube on the washers and nuts on the top of the head........

absolutly.......just get the allen wrench that fits into the top of the stud and back them out of the block......

yep with a power brake booster and an heater box in the way it cant happen I've tried it lol.........gotta do it the way i do........put the heads on and then thread the studs in though the heads......just make sure you dont over seal the bottom threads and end up with rtv oozing out onto the head surface.....

you just hand tighten the studs? thats all before you put the heads on?

Ive seen videos where people use two bolts on the stud to tighten the stud down good.
