I have just Installe a cometic head gasket on my car because I have plans for boost in the near future. I know that the cometic lowers your Compression from 11:1 to 9:1 this obviously cause power loss. Besides that are there any symptoms that come with this on a still N/A motor thanks!!

 

just the power loss. my friend of mine bought a formerly turbo'd car and that engine still had the gasket.

 

You may be able to run 87 octane now!

 

im curious to see how much power it makes with the headgasket
