Shane from the 2012 CMB VAC 45 Spec sheet " Squish Clearance 0.012" / 0.3mm// Squish Width 0.167"/4.2mm and Squish Area 69.80%" It does not list what head shims are used. Most boater's running high nitro, 50% + are running .008 " HC

You can't just put shims in and call it good, you havta measure the clearance either by mic/solder, plastigauge or one of the dial gauge adapters.
