Unkey one or two of the the easy valves to access. Move the valve up and down by hand to determine if the valve gets real sticky toward the full closed position.

On my engines i found that once i pulled the valve closed real fast and real hard by hand that i could not open it nor budge it by hand to open. I had to use a small hammer handle to drive it open the first 1/6" or so to break it loose. This was only on exhaust valves. Not intakes. The intakes were just fine. It took A LOT of snake oil soaking and twirling and working of the valve by hand and drill motor to get the valves freed up thru the full length of travel.
