for my a6, z6, y8 hybrid build I need to use the d16a6 head gasket to keep the compression ratio in the area where I want it (10 to 10.2:1). Therefore to do so I need to use the a6 headgasket. I heard it is the old material and not metal so its deteriorates quicker. Are there any steel headgaskets on the market like the y8 one that are the same thickness...or rather could I use 2 y8 headgaskets for example?

 

according to this website,,,the a6 headgasket is 0.048 inches thick...therefore i guess ill have to custom order a steel headgasket for dseries thats about 0.050 inches thick.

just use the z6 head gasket. it shouldnt affect the comp ratio to awful much. it will give u more comp which is better

 

Honda has an all-metal head gasket that is a direct-replacement for the old A6 composite gasket...same size, too.

 

thanks again for the info...also I have to use the a6 equivalent or one that is 0.050'' as I am using this engine through the winter for4 months...then in the spring ill use the y8 headgasket and be up to about 11:1 of a CR.
