Cylinder head stripping

Spent today stripping the cylinder head, removed the cam shafts, springs and valves. All of the exhaust valves had a thick layer of coke which took a while to remove. The inlet valves were cleaner but a couple had exhaust coke so some of the tappet shims will need adjusting to get the valves sealing right.

The head needs cleaning along with the block and then the remaining carbon deposits carefully removing without damaging the aluminium. The valve seats will probably need re-cutting as the deposits will likely have scored deeper than is practical to remove by grinding/lapping.
