My A10 engine block is just getting the work done in above pics, The AB man is doing the front plates and head gaskets but Xmas is here so most places are tight for any new orders and work but progress is happening.

Some of the later heads have extra drain holes which will need to be plugged up, drilled and taped on the sides for brass 90 degree fittings then to a 4 into one T setup to drain into the side of the sump or dizzie hole.

The smaller pulley setup will require a shorter timing belt and tensioners moved in closer on the inlet side and one further downwards so if this is too much for peeps to try and work out you can wait till I sort it out then choose this head if thats what you would like or if you want smaller pulleys. However take note Im doing an A15 later after I finish the A10 overbore motor.

The Z6 head is the one Im attempting on the A10 and last pic shows the extra drain holes which can be Teed up and sit hidden by the inlet manifold and carbs
