Next after that if that doesn't work, take a big *** flat blade screwdriver through one of the inspection cover holes in the transmission and wedge it between one of the teeth on the flexplate and have a helper hold it while you try again. It will come loose. If not you need a new impact gun or more air pressure.
Kinda hard to do when the heads were off, doing a h/c swap...

Uhm well that would explain it dude. You're f'ed unless you can lock the crankshaft in place someway. Should have taken the pulley off first. Your only choice is to lock the flexplate up or get a rod through the blancer and have a friend hold it to lock it from turning over. Otherwise install your new heads and then take the pulley off.

Yea, there's a couple different methods...there are flexplate turners, flexplate locking tools, and the old big screwdriver wedged against one of the teeth trick...

I actually used a big nylon strap wrench around my crank pulley, wedged against the ground or frame (can't remember), it worked like a charm.

Yea, I actually don't like that method, but it's common practice for alot of folks. Even through one of the holes in the flexplate I'd be concerned about the flexplate getting damaged, that crank bolt is effin tight
