VALVES REMOVE FROM THE N ENGINE

First remove the manifold and the tappet covers.

Fabricate a tool from a big heavy common screwdriver that can be inserted into the valve ports and used to push the valve guides down enough to remove the horseshoe retainers that hold the valve guides at the bottom of the valve guide just above the spring.

When the retainer is removed then it is possible to drive the whole valve assembly out the top of the engine up through the valve port .

The spring keepers can then be removed and the valve assembly disassembled.

Seals are only used on the intake valve guide and they will be the ones that are the hardest to remove from the block because of the old seal being like hardened glue on the outside of the old intake valve guide. Only use guide seals on the intake when reinstalling the valve assemblies.

Body of Message:
The best way I have found to get the valve assemblies out of the block is to use a big flat/spade screwdriver that has been ground down about 1/8 inch or so just up from the tip end about a 1/4" inch or so and long enough space ground down to let the cut out come out past the side of the block.
Place the screwdriver/prybar into the valve port on top of the valve guide close to the valve stem and pull up on the screwdriver/prybar to push the guide down enough to pull out the horse shoe keeper.
Next take that same screwdriver and place the tip end on the spring close to the end of the valve guide and smack it a few good ones with a hammer to drive the guide/valve assembly out the top.
Once it is out the top you can depress the spring and take the keepers off to dis assemble the units. Don't loose the little cup thingies that are on the bottom of the exhaust valves if it has rotating exhaust valves in it.
Only the intake valve guide should have seals installed on them when you go back up. None on the exhaust valve guides.
