  • Q: Head gasket size   kingsrt43 years ago

      A:  The OEM head gasket is .6mm thickness and this is 1.3mm. So this head gasket is twice as thick as the OEM one which will lower the compression of your motor. The bore size of the gasket will be ok with the bore that you have on your vehicle.

  • Q: Thickness  boycottcorn5 years ago

    What is the difference between .051 head gasket and the .040 head gasket? My brand new timing belt decided it didnt want to be one piece anymore and the heads need to be ripped off. Aside from a tuner an intake, up pipe and down pipe its stock. What would you recommend?

      A:  A thinner head gasket will give you a higher compression ratio. You must make sure not to go too thin to the point where the piston may contact the valves. This can happen if the block or heads have to be machined and you run too thin of a gasket.
