I would like to find a thinner head gasket to bumb the Compression at bit higher. But the problem is that who makes thinner head gaskets, for my B20vtec whit 85mm bore? Because the only ones i can find there makes, thinner head gaskets is for 81mm-81.5/82mm?

 

What exactly are you trying to accomplish?

 

Just that i want at bit more compression And i know that i can get the head milled, and it maybe is the right thing to do. But now i want at "thinner" head gasket.
and I can not find anyone there makes a thin 85mm gasket?

 

Your goal is just too vague sir. You're attempting to reach a compression ratio of what in order to gain what?

 

To reach a higher Compreesion Ratio...

 

Take a factory MLS gasket (three layers) and pop the rivits out that hold them together. Remove the top and bottom, use the middle, der you have it. Torque the same way. Poor mans thinner gasket. Works as well to stack them too, just not more than five is advisable.
