When installing a block guard, how far in should it be installed? Should it be flush with the deck or gasket surface or should it be lightly tapped in evenly about 4 or 5mm below the deck? Thanks

Never tap the block guard in. Sand down the block guard to the point where you can easily place it into the water jacket. You want the block guard to lay a bit underneath the deck, your restricted by the tops of the coolant jackets as to how far you can actually place the guard in.
