Default Who has been using a cometic head gasket?

I am looking to install a thinner gasket to increase compression to 11.3:1 instead of doing any head milling. Does the valvetrain need to be modified in any way to accomodate the thinner gasket?

Thanks for any input.

I am using the cometic headgaskets and love them. Reused them 3 times with copper spray and all is good. A thinner gasket will help remove hot spots by decreasing hot spots.

How is the life span of the gasket? Does anything need to be altered? PCM? Fuel Injectors? Fuel Pump?

I am thking the pushrods must be altered.

You should not need to alter the PCM by changing the quench area via head gasket thickness. It's possible that you may need to alter the fuel *slightly* due to the more complete combustion process. Decreasing the quench area will squish the air before combustion takes place forcing it into the chamber. PM me if you need any help
