new apex seal dimmensions

i know a 2mm apex seal is damn near 2mm thick, but how tall are the seals? meaning, as they wear, they will get shorter. i don't want to order new seals unless my existing ones are worn. they only have 8k miles on them and i've lost a lot of compression.

PS: without taking the motor apart, can i just poke my finger in the exhaust port and push on the seal to see if there is any pressure behind it? i mean, if there is next to no pressure then i'll know the seal is either worn or maybe the spring is broke. if there is a lot of pressure, then i guess the seal and spring are still good and i might be loosing compression somewhere else.
