MLS copper spray

[Aproductions]

I have read some different articles some saying do/dont do.


Would you copper spray a MLS head gasket (for my 420a)

I have used copper spray on both MLS headgaskets I put on my 420a. And neither has failed at over 20psi of boost. Some say dont use and other do, its your choice but I have never has any issues because of it.

Just use it.. Most use it. I do, have yet to have an issue with a HG from using the spray.
