With my finger in the number one cylinder i can feel the air really strong trying to push back like there is more the 50 psi. Im going to buy a new presure tester since the one im using looks really old and beat. I am going to find the average of all the cylinders too
Its my first time building an engine so yes i do know little about how to find where the problem may be. Its out of an f150, its been out for about 5 months and sitting on a pallet with me buying parts and replacing stuff. New cam, lifters, timing set, and mustang front mounts. No matter what cylinder i put the compression tester on air leaks right back out when i stop cranking. This motor will be going into my 94 ranger. The motor is carburated. I did the test with all spark plugs in and with all spark plugs out and same resultsEven asking such a question tells us you know very little about what you are doing.
So start off by telling us about the engine, where and why you have it and what you will do with it if it does run.
If the engine has sat for a long while and you don't know how to do a compression test you could have NO PROBLEMS and only THINK you have them.

I got one, still 50 psi, someone here said put oil in that piston and try so i did and it jumped up to 130 psi so im going to be replacing the piston rings and honing the block while im at it, ive already tore everything down to the block, crank, and cam, everything else it off
I had a whole set of lifters pushrods and roller rockers i got from this kid off his mustang but they never worked out right so im getting new rods and using the stock rockers
