    Hello
    So i have a problem my cylinder head is slightly scratched and a little bent so the regular metal gasket doesnt seal it (coolant gets in the bore) but i found a solution a athena composite head gasket that nicely squished the head together but it was time for a rebuild and i had to tear it down tried to fit a normal headgasket but that didnt hold (found out the hard way) so im in need of the thicker athena composite headgasket but i cant find it anywhere and i cant remember what store i bought it from.

    Thanks for any help!

        Several options

        Can you not skim the head and barrel and remove the imperfections, then space the barrel with two bottom gaskets?

        Can you not get yourself a reusable copper head gaaket. They used to be all the range a few years ago.

        You could always contact an engineering firm like PJME to machine an o-ring into your setup to bypass the imperfections.
