You can buy an original GM set for one head from sponsers here for about $25.

Yes.

They become worth every penny if you plan on taking the heads off a few times, plus you have the added strength

OK guys it is time to get the facts straight. The GM head bolts are not "crap", they do not "go bad", and GM is not "greedy" in the price of their head bolts. The head bolts are designed as a "torque to yeild" fastener... they are turned and stretched to a certain point to apply the proper amount of pressure to their appalication. Once they have been stretched they will not apply the proper pressure to do the job they were designed for. Thus they were designed to be used once and then discarded. If you are going to have the heads off of a engine often or you want a superior fastener then I would suggest a set of ARP studs or head bolts. They are torqued to a foot pound specification and can be used over and over. They cost a little more than the stock GM head bolts but are worth it to me as I change heads from time to time. I all depends on your situation. The LS series of engines are a mericle of modern engineering and design. The performance and durability that they have are truely superior.

Seriously. Lots of uneducated people in here.

Many modern engines use torque-to-yield head bolts. They maintain the proper torque much better than conventional bolts, and prevent head to block sealing issues.

It has nothing do do with being cheap or making money, its about producing a quality product.

You just proved EXACTLY what I was trying to point out. ARP is a superior fastener, costs more and can be reused. Hmmmm...GM use to sell motors with reusable head bolts. Hmmm...Sounds like they took a step backwards...what could that be for...$$$$$$$...maybe?!!

If you want to believe the hype that is being fed to you that is fine. However, you proved EXACTLY what I was trying to point out.

I am grateful that GMs bolts are not overly expensive and I use them, myself.

Paul you need to understand the technology and engineering being discussed before you make statements like that. Do your homework sir and then you will understand what we are trying to tell you. The LS series engine is designed for a 200,000 mile life.

I would imagine that the heads don't often come off for most people, cam only cars, bolt on cars, bone stock...those people make up a huge majority of the people who currently own a GM LSx motor. So you would never need to replace the bolts that GM has come with the car.

That's just efficiency and not wasteful spending. GM isn't making money off you buying ARP bolts which most people do for the added strength and the fact you can reuse them.

I appreciate you pointing out some of this info.
I just want to make sure I have the "bottom line" correct here...it isn't like I've never had bad information before .
So you are telling me that...GM bolts are better for a 200,000 mile motor than the ARP (or any reusable) head bolt is. Correct?????

Are GM bolts better?
No.

Are ARP bolts necessary on a normal 200k LS motor?
No. The GMs are just fine. If the heads come off two or three times in its longevity you are still saving money by buying the GM bolts. No need for ARPs in that situation.
