    HKS 3mm Copper head gaskets reused?

    How many times can the be reused?

    I have some on my Z and have installed them twice.

    They were not cheap and I would like to reuse them again.

    Ask yourself. Do you want to take apart the engine again due to a leaky head gasket? Replacing one is just peace of mind. If you do re-use it I would highly recommend letting a professional engine builder go thru the gasket to determine if it's reusable.

    Sometimes I feel like I'm the only one still using OEM headgaskets

    You're not. Unless you're going for lots of boost, the stock gaskets work fine.

    I've had the OEM gasket up to 26psi with no issues. That was with OEM head bolts too. I like to live dangerously lol

    I have had said gasket for like 20 years.

    It was super expensive back then.

    I was just curious. From what I was told back then the gaskets were resuable.

    This one has been used 2 times already.
