At what point can we no longer use an oem head gasket? I ordered a kit that has all my gaskets, belts and stuff. It included an oem head gasket and I think I will just use this if it will work. From what I gathered while searching it seems that it will be fine, but I want to make sure. The engine has a 1mm overbore.

 

1mm is nothing. The OEM gasket has nearly that much clearance per side.

 

Thanks for the reply, exactly what I needed to hear.
