After a few searches I have read where several people say they know someone who has and their setup works fine, and others saying you can't use them due to the larger diameter bore. Too many mixed opinions for me to make a good judgement call.

My setup is stock shortblock LS6 with Trickflow 215cc heads.

What I'm looking for in this thread is a clear concise answer of either "YES" it is possible to use LS9 head gaskets on a LS1/6, or "NO" it is not possible to use them.

If someone with first hand experience would like to chime in, it would be greatly appreciated.


Thanks and Happy New Year!

I've heard that they were probably the best gasket to use on a boosted setup, but all I could find was confusion when I searched for factual information of someone using them on a stock bore LS1 with stock sized combustion chamber heads.

I appreciate you guys sharing your knowledge.
