Q: Better than thinner gasket? PLN 33 1 year agoAnswer
Would this thicker gasket seal better than the other thinner cosworth gasket? Since other after market gaskets like grimmspeed's exhaust gaskets are thicker than OEM (7 layers as opposed to 3).
A: Thinner or thicker head gaskets will not have a difference in layers, it is the thickness of the metal gasket to provide clearance to the pistons from the valves or to alter compression slightly depending on the setup needed.

Q: Advantages? Andrew Jarvie 2 years agoAnswer
What is the benefit of going with a thicker HG?
A: A thicker head gasket can decrease compression on a standard head and block. If either of these have been machined down you can make up for the loss of material with a thicker gasket as well to keep a close to stock compression.
