Icon4 PO316 - Misfire(Compression) Heads?

Hey guys i have a 2005 Mazda B3000, which means its a 3.0 vulcan OHV. I recently took my truck in to find out why the engine light was coming on. It was on, gave it a few days, it went away, and then it came back, so i figured it was a legit issue. turned out to be a 316, we compression tested it and all the cylinders were good except for 4, which had a 8% loss in compression. I've heard a bunch of things like rings or a possible crack but I'm kind of on a tight budget (college kid) so any tips would be helpful. If it comes down to replacing the heads i've heard the flex fuel heads are a little stronger and if there are other easy mods to do while the engine is cracked open please let me know.
