Hey James.
A leak down test doesn't have to be fancy. Break open a spark plug and weld,
braze or even epoxy a piece of tube into the metal body. Put a hose and clip
on the tube to connect the plug to an air source. Very low pressure
(especially if you used glue!)will be more than enough. Your ears will tell
you how the compression is getting out. Zero pressure is a lot of leak.

I still think that you should do a leak down test......this will tell you if
the valves are the cause and, if so, if it is exhaust or intake....it will
give you some direction to look.
