It will run. Yes the comp will probably rise when running temp.
When I take compression tests, I pull all the plugs and turn it over so there are 3 compression jumps in the guage. Watch how far each goes up. The higher it is on the first jump the better.
example: 60-75-95 is better than 45-70-95. (NOTE: these numbers are just examples and not to be confused with what the compression numbers should read)
Try this and see how consistent the numbers are. I would also assume that you have a manual for your truck which will be the source of most of the information you need. If not, try
