Default Back Firing Engine Compression Test

Well I did a compression test on all 8 cylinder to see if that would help any . Well I thought the engine was rebuild not long ago and I am right .
Here is the cylinder results .
#1--150
#2--150
#3--150
#4--150
#5--140
#6--150
#7--130
#8--150

All spark plugs are clean with no carbon .

I would say it's didn't have a valve job or a terrible one done to the heads ! Maybe a bad guide , maybe a bad valve , bad valve or a bad seat IF they were replaced . I also think the intake gasket is leaking as well .
