With our choice made to install an all-new rotating assembly, we turned our attention to preparing the block. Each deck was given a light 0.006-inch cut (two 0.003-inch passes) on the JMS Block Master 85-B to restore flatness for gasket sealing. Remember, aggressive material removal (0.020 or more) will decrease total the deck-height measurement and can affect compression ratio, piston-to-valve clearance with high lift, high-overlap cams, hydraulic lifter preload, and intake manifold alignment. Less is more when it comes to decking; thinner decks are less rigid. View Related Article
