Valves

 This is the cylinder which had lost some compression. The culprit was a worn or improperly installed stem seal on the exhaust valve. Ideally the compression will be restored after resurfacing and lapping the valves and seats. All new valve seals will be installed.

Valves, before and after surfacing. The small diameter valves with the fatter stems are sodium filled exhaust valves. These help move heat from the valve into the head where it can be absorbed and drawn away through the coolant galleys.

Honkin big cylinder head

This is an M110 Cylinder head, almost clean. It's a very nice casting and machining. It was really mucked up. If necessary a cylinder head can be cleaned by hand.

Ooh hello, what's YOUR name?

At the junkyard today, and what should I see but a blue Ford with a toploader 4 speed. MMMM, TASTY
