   it seals the head from leaks for one but that one is pretty obvious.

   it also adjusts the compression amount on the engine. a thinner gasket will raise the compression while a thicker gasket will lower the compression. the amount of compression affects how well the engine will run. nitro motors are factory tuned to a proper spec with a proper compression ratio. so changing the ratio is not advisable.

   as an example. no head gasket on most nitro engines will cause them not to even run due to the large increase in compression. if you are able to get one started it will not run well. its always best to stick with a factory spec head gasket on these engines even when using a different cooling head.
