Anyone have a trick on how to keep the gaskets in place while trying to bolt up the headers? I have tried exhaust sealant with out much luck.
Thanks Brian |

Cherry red, let cool slowly, don't dunk in water.

At least that's what I've read (and done). When properly annealed, dropping the gaskets on the ground will give a dull "clunk" sound rather than a ringing sound. |

When properly annealed, dropping the gaskets on the ground will give a dull "clunk" sound rather than a ringing sound. No! Quenching hot metal in cold water hardens it. Do NOT do that if you want to anneal copper to conform as it gets bolted up. (While copper, silver, and brass CAN be quenched during annealing, it's not needed, so better just use quenching for hardening and keep it simple.) The whole point of annealing is to make it as soft and pliable as possible. Let it cool slowly. Otherwise you'd be better off to just bolt it up without any treatment, as hardening it is only complicating it. If you aren't sure, just bolt it up and retorque after a heat cycle. It's really not necessary to treat them. A bigger problem is when people don't realize there's still an old one stuck up in there and you need to use a pick/hook tool to get it out. |
