To the best of my knowledge, there is no magical fix for a blown head gasket. Unless you had a faulty head gasket,(which would mean you just have to replace said gasket), you probably have a warped or cracked head that caused the blown gasket. Your only course of action is to find out what caused the gasket to fail and fix said problem. Sorry to deliver bad news.
HG on a 4.7 isn't small job. I'm not trying to be a jerk, but if you don't know what those tests are, you may have gotten in over your head doing the job yourself. You really need to be able to perform those tests to fully diagnose the problem, although it sounds like a safe bet that it will need to be done again. Did you check the heads before you changed the gasket? What prompted you to change the gasket the first time (same symptoms or different)?

"Bought, Not Built"
ok the motor in my 01 wj came out of my other 00 wj that i rolled, now when the motor was in my other wj the motor was putting some gunk in my
radiator so since i was pulling the moter out i fugure ill go ahead and fix it up so it goes in with no problems. so when i started to rip it apart i found that the heads where in bad condition, so i went and got some rebuilt ones for about 500 buck. when i put the motor back together with all the new parts, the motor was having trouble stabalizing and was blowing my ASD fuse. so i took the jeep to a shop and they could not find the problem(was there for a month) and said it was electical, so i then took it to and electric shop (was there for 3wks) and nothing the guy did not figure it out. By that time it had been 2 months that my jeep was out of sevice and was starting to get fustrated. i then checked my dip stick and there it was ! the water and oil where mixing. the dumb *** mechanic did not check my Jeep right. when i disassemble the motor again i found water in my cylinders. i took the heads back to the head shop and they told me the heads where warped and that it was MY FAULT but the jeep hadent been moved at all plus the motor want staying on the first place for me to over heat it. long story short, so they resurfaced the heads for 20 extra bucks apart that i had already paid 500 buckd for them, i put them back on, finished puthing the motor back to gethere and it had been running fine for a week and not here i am. sorry i wrote so much.
