Check the valves by pouring a liquid into the chamber.  If none leaks out, you should be good to go.  You can replace the cam chain with a linked chain so you do not have to split the cases...Larry

Larry, are you saying to put liquid in the head while it's off the rest of the engine, or does it need to be reassembled to test it under pressure?

When the head is off.  If the seats are bad, liquid will seep out of the seats. I use WD40, heard of people using gas or water...Larry
