hi there are three long bolts holding valve bodies together. sometimes from the factory there is a small shim on one of the bolts near a valve section. this is because of tolerances in machining parting faces
loosen one bolt at a time and see if it makes a difference, if it does measure gap with feeler gauge and install small shim around that bolt at that section
