After WD-40 is sprayed on the cutter head, tap the cutter head on each side of the blade. Do this several times to each blade . Let it alone for an hour or more. Then use a heat gun, not a torch on the cutter head, but not the blade.
Heat for about 3 minutes . Tap the blade from one side , if it moves at all then pull the blade using a vice grip.
If possible insert a screw driver in one end and try prying the blade up. I have done this once with a 16" jointer that was in an old garage for years. This jointer was a 4 blade square cutter head with Babbitt bearings. My boss got it for the taking.
Was worth the effort to restore it as a new or used 16" jointer was cost prohibited.
We cleaned up the cutter head, replaced the blades and our millwright poured new Babbitt bearings.
