I've tried searching

....what is a good rule of thumb for engine head shimming? The manual states that if you run more than 25% NM to shim 0.1mm, but I'm not sure it's that simple. Can someone help? I am going to be running 30% Byrons with either 9% or 11% lube.
Also, does anyone know what piston/sleeve/con rod I will need once it's time to rebuild?
Thanks guys!!
