Quoting: Anonymous Coward 47482356 So e people on the vids say not to use certain gaskets like manila envelope or cardboard for high heat applications. I think that's because it'll turn it into charcoal, at least those 2. |

User ID: 65945302 United States 01/23/2018 09:09 PM Report Abusive Post Report Copyright Violation | Inquire about the melting point of aluminum, that should be your answer. You can buy good gasket product at a parts store. Quoting: bigD111 Hmmm. Melting point of copper 1,984F Melting point of aluminum 1,221F You should be all right then. Get a tube of permatex hi tempto use with it. deplorably republican |

The hottest a two stroke cylinder head should get is 450 degrees continuous running, 500 for short periods. [link to motoredbikes.com (secure)] I think the aluminum gasket will work for this application. |

But removing gasket thickness required modification of port timing along with higher compression. (again, 2 strokes) 4 stroke it would merely increase compression. |

That thickness also affects fuel delivery timing in 2 strokes (you didn't say 2 or 4 stroke, or I missed it.)

The gasket was kinda thick like the beer can not a soda one. Quoting: Anonymous Coward 74785542 soda cans are deep drawn from 1100 aluminum (pure, soft) Dont know about the beer cans. If they are deep drawn prob 1100 Government is a body largely ungoverned. |

Get one of those disposable aluminum baking pans... it will be a bit thicker and larger and won't be curved so it should be easier to trace out a gasket. If you want to match the original thickness of the head gasket layer it 3 deep, that's how modern metal head gaskets are actually built. |

Anonymous Coward User ID: 75997524 United States 01/23/2018 10:31 PM Report Abusive Post Report Copyright Violation | Aluminum squeezes out when under pressure. You will never keep a constant torque on a pure aluminum gasket. Usually when you see aluminum used in a gasket it is layered on top and bottom of another stable core material that will not squeeze out while the aluminum seals scratches and dents when it flows under pressure. |
