head gasket

I have a 7mge bored .50 over can i use the stock head gasket? thanks.

No, the stock gasket bore is too small, and will encroach into the cylinder. IIRC, most quality aftermarket gaskets are available with larger bores.

Your right. You would have to use a headgasket with .050 over bores. If your planning to run a MHG, take it to a machine shop and have them mill it to match your deck. The machine shop you had your block bored at should be able to help you out.

.50 over? Are you talking a standard Toyota piston that is a half millimeter oversized?

You must mean .5mm because afaik there is no .050" size piston and if you did .500" you would have no more cylinders lol. .5mm= .020" over

If you are only doing 0.5mm oversized, stock gasket will be fine. If you are going .050" oversized, it will likely not work for you.

oh i made a mistake i thought it was .050" but i got i bored .020" over, i called my machine shop and he told me that i should be fine with a stock bore head gasket, since it was just a .020" bore.
