I was going to stick with oem stuff with my rebuild of my b18c1, but the cylinder walls were a little messed up and the machinest recommened an overbore done to fix it. So, we went from the stock 81mm to 81.5 and put in some 10:5 JE pistons and eagle rods. I haven't assembled the engine yet, but I have all the gaskets from when I was doing the oem build. Can I used the oem head gasket with the overbore? The gasket came in a top end kit from inlinefour and should be for a 81mm bore. Will the .5 mm make a difference here?

 

nope, you're fine...
