use a large micrometer across the heads, from the cylinder contact surface to the flat area that the cam tower contacts. hopefully they're all the same. 85.5mm is stock if i remember right. most shops cut 0.25mm at a time. then the base gasket which measures 0.25mm is increased to 0.50mm by either doubling them or using a single thick one to compensate for the amount removed. so if they were cut, the measurement would likely be in the 85.25 range. the base gaskets themselves can get squished out of shape too, so they should be replaced in the troubleshooting process.
