If you check the valve to piston clearance without the head gasket, head directly to the block, this will give you a big enough clearance when the engine is assembled. Gaskets are approximately 1.2mm thick when torqued down. With boxer engines it is normal to have the block decked, not remove material from the head. You may find that you will need larger diameter cam belt tensioner to compensate for the material that has been removed from the head or block, depending on which way you deal with this situation.
Good luck with the project.
