The entire deck of the block is machined out on CNC & a CNC billet deck plate is press fitted into the top of the block - it's 24mm thick higher quality alloy & gives 360 degree support to a flanged liner, the deck plate itself incorporates the centre head bolt holes so it has as much support as possible all the way around.

Should stop your bore flex.

At a cost.

Developed and produced in Aus!
