Cylinder Head gasket for overbore engine??

[subaros]

I want to know if i can use OEM head gasket size if i overbore my cylinder to 0.02mm or 0.05mm for example.

Thanks !

yep i believe you can use the stock gasket up to 40 thousandths bore

That bore size does not affect the gaskets as the material is taken off the inside of the sleeve. So yea you can use the stock gasket.

Sure it does. Just as you stated you take material off the inside of the sleeve diameter which means that you have to ALSO get a head gasket larger in diameter. If you did not do this then your head gasket or sealing part of the head gasket would protrude into the bore of the sleeve. You can go up to an 84mm overbore piston then you have to use a different gasket.

I hope you don't plan to re use any gasket esp. the head gasket.
