Compression Check Numbers

What should the compression check numbers be on a stock Straight Eight?

I removed all spark plugs and placed a compression gauge in each cylinder when the engine was hot and came up with numbers that were between 107 and 118. The numbers were generated after cranking the engine for 5 compression cycles using the starter.

Are these normal readings?

This was done after I adjusted the valves today with the engine hot (took about 45 minutes to complete the valve adjustment procedure) using the Peter Toat method.
