Default Tips on removing exhaust manifold gasket?

I took the header bolts out and just let the headers hang.. the paper gaskets are stuck to the heads on both sides of the engine on the very back. Iíve tried scraping with versions sized screw drivers but canít seem to get it. Even if I were too itís stuck on so well it just kinda chips off.

Any advice?

Spray oven cleaner on a rag then dab where you need to. Don't leave it on there long, just a couple minutes then wipe off then repeat till gone

Same way i scraped off my composite head gasket. Razor Blade and a vacuum. Cover the ports ups or take the heads off.
