Yes, the machine shop will want the main caps and the fasteners you are going to use. This would go for the head studs or bolts your going to use as well. (If they are going to hone with a deck plate). They will want to torque the main caps on and measure the housing bores. Then line hone if necessary. Then they will bore/hone with the main caps torqued in place. This will pull/push and stretch the cylinders similar to their shape when operating.
