Glad to see you are making progress.

I assume it was not a difficult job when you got into it..

As you will note from all of these links, your next step is extreme cleaning - inspecting the cylinder head parting surface for cracks.

If no cracks are found:
* Remove the valve springs, use a dial indicator to check the valve for slop in the guide.
* If the guides are bad = have the cylinder head serviced = new guides + reface the valves - seats.

With any luck, it should be running again in a few days.
