Ls9 Head Gaskets
Ls9 Head Gaskets I'm in the middle of putting my motor back together and need some info on head gaskets. Motor is a 2001 ls1 with a single turbo. I plan to run around 10 pounds of boost. The bottom end has weisco 3.905 pistons and callies compstar rods. I've read mixed opinions about running ls9 gaskets on the smaller bore motors. I called a couple of sponsors and they only recommend using a ls1 multilayer gasket. I didn't even know they offered a multi layer ls1 gasket. Please let me know your thoughts on what to do.
Thanks,
Thanks,
It really depends on what head you use.

Those are the gm mls ls1 head gaskets. Normally it is better for quench, sealing, and cr to use a gasket that has a tight clearance on the bore.
If you are using an 806 or 862 head youve got to use a special gasket due to the notch in the head deck surface.
These are them

That being said, yes of course alot use the ls9 head gasket and have good luck with them.
Here they are

I don't get it. If someone has the option to put something on their car that is safer, more reliable, or provides more margin for error; why wouldn't you?
I don't plan on 1000 WHP. More like the 600 range. My tuner recommend the ls9 gasket. He said with my pistons and heads they would lower my compression a little. Just wanted to make sure it was ok to use the larger bore. What about a cometic gasket?

Is there a reason all you do now is post about using lesser quality stuff on peoples cars?

What part of his concern was about the bore size relative to the gasket...and the LS9 is clearly not a better fit in that respect.
That would be like telling him he needs a Callies Ultra Billet crank instead of a stock crank. Well it will be safer and more reliable wont it ?
And why do people make **** up without reading ?
Where did I ever say forget LS9 gaskets ?
Where did I ever say forget non projected plugs ? Even more so since I've given various recommendations of such plugs where they have been unable to find them ? Whether of course they need them or not.
And more often than not...yes screw MAF's
Do you understand about using parts suitable or appropriate for the goals specified ? Yes anyone can spend more and use more expensive parts...but are they always needed or of benefit ? Of course not.

)GM MLS gaskets are cheap, and very very well proven for "safety and reliability" compared to others, and as a bonus they're cheap and available everywhere.

So how is an LS9 gasket safer and more reliable on an application that wont come anywhere near to stressing a regular GM MLS gasket ?

And the other "secret" thread, multiple people are talking about the safety aspect of nonprojected tip plugs....and you jump in with the "I've ran projected tips for years with no issues, blablabla." You posts infer there's no benefit to anything done for margin or safety. And nonprojected tip plugs are just as cheap as projected tips

Your first post basically tells everyone unless you're making 1000hp, don't bother with LS9's. And to your question, when are LS9's safer.....how about the 1st time you have a hint of detonation or a bad tank of gas, you won't puke an LS9 gasket, where its much easier to do it with a stock MLS.

And as stated many times in the "secret" thread as you call it, there are no secrets. There is simply good tuning and bad tuning.
Can you show me a single build where an engine failure has been directly/solely attributable to using a normal projected plug...where a non projected would have prevented it ?
And is there a benefit in a build like this ? Where is the evidence ? Just how much additional safety margin do you need...over an already safe build if tuned correctly ?
Just safe safe...or sooper dooper safe....or sooper doper mega safe ?
im using ls0 gaskets on my ls1 with arp headstuds and been 2 yrs and 5 or 6k miles . Others have used them . It may not be the correct size but it works . the ls1 mls gaskets should work fine too .
So dont buy bad gas ? Dont have a moron tune it so there is a risk of detonation ?

The point is not EVERYONE is as perfect as YOU claim to be. People blow stuff up all the time! All the stuff we talk about in the secret thread is how to mitigate problems and give the average Joe more margin so he DOESNT blow his stuff up. Why is that so hard to understand???
But if someone is blowing **** up all the time...you can be sure it isnt because they used LS1 gaskets instead of LS9...or projected plugs instead of non projected.
It isnt margin's they need....it's simple tuning knowledge. Dont run too lean, and dont detonate the **** out of it. In fact....never ever let there be detonation even at the mildest onset of it.
Very simple and generic rules that lead to reliable running.

Which I'd tend to agree with. However, only from a second hand perspective. I've never used LS9 gaskets.
The stock MLS, should suit this application very well. Without detriment, IMO.
