Cylinder block deck spacer for the Honda GX340, GX390, Predator 420cc, 460cc and many other big block cylinder cylinder Honda GX based engines.  Our aluminum block spacer is 1/2" thick and allows you to increase the deck height of your block to run a longer rod, more crank stroke or a different piston compression height combination.  Our deck spacer comes with longer head dowels which you will need to cut to length once you mill your deck surface to the height you are needing.
