Spark plug reading

Got time after work to swap in new NGK plugs BPR4ES, gapped at 0.035. I thought I may as well do a compression test as I hadn't done one yet.
Throttle wide open, Coil unplugged, all plugs out
Cyl psi
#1 167
#3 172
#5 167
#7 155* dry, added oil 164
#2 165
#4 182
#6 175
#8 175.

#7 was low so I oiled it and it helped but was still lowest at 164, it was also the most fouled.
Drive tomorrow
Thanks all.
