Nice rebuild, Glad you took the time to have the block checked out properly and pressure tested and chemically cleaned.
As you know mines going back together as we speak.
I've worked out your "Cam Sprocket locking tool" Just made up up in the garage, and put it into place ready for dropping the head on. Just waiting for the Exhaust and Inlet Gaskets to arrive on tuesday, Hopefully we'll be running tuesday night.
I see another session of burning the midnight oil coming on.
