In order for the extension to fit over the compressor I had to cut the inside of the tube to the right size.
First step complete
Next step mill out some holes in the sides of the tube (so you can remove the collets from the valves)
Not massively tidy, but does the job - stil needs a clean up.
Extension mounted to spring compressor
Removing the valves from the engine
loads of clearance and no danger of damaging the head
The head with all the valves removed
The intake valves and valve seats look great, but the exhaust seats and valves need re-grinding. They are just starting to pit. All in all everything seems to be in very good condition.
All the valves, springs and collets arranged in order waiting to be cleaned up.
Clean valves! This took a lot of time! The exhaust vales were cakes. Used a technique from Jason (GreatOldOne) placed the valve in drill and used increasingly finer sand paper to take the layers off and then some metal polish to finish it. The intake valves just need a run over with 1200 grit & some degreaser, then metal polish.
