Next step: I matched up the 2.5L head gaskets to the 2.2L gasket. Some water passage areas will be blocked by the 2.5L gasket.
I used a piece of wood the rest the gaskets on then clamped a piece of wood each side of the area being drilled. This helps drilling through the multi layers and keeps the metal dust from going between the layers. Took me 1.5 hours to do one gasket. Then I blew out he gaskets with air and double checked there was no metal in between the layers.
I would post some photo's but have no site to host them.
