Hope your heads aren't cracked. Use an HVAC inspection kit. Spray the mating surfaces with florescent penetrant dye and look at them under a black light with the glasses to make sure it's just the gasket. If they're not bad, you can resurface them at home with a heavy pane of glass covered in emery cloth.

Really, you've just got to use an abrasive that's harder than gasket material, but softer than the cylinder head. I'm not afraid to use steel bristle wire brushes on iron, but I wouldn't use a steel bristle rotary tool. Brass wheels wear out fast, but they shouldn't hurt anything. The DIY thing is to scoot your cylinder head mating surface around on a piece of plate glass wrapped in emery cloth afterward. I used scrap glass from an antique aquarium. Marble or granite counter scrap would work. It's a sliding scale of how valuable your time is. You can take a long time and do it cheap or you can pay a machine shop to do it fast, or even not do it at all, but having taken it this far apart, I would face them.

NMWR 9-2815-274 : Using a straight edge and feeler gauge, check flatness of cylinder head to block mating surface. Flatness of cylinder head (11) must not vary more than 0.002-in. (0.051 mm) in distance of 6 in. (15.2 cm), or more than 0.006 in. (0.152 mm) overall. Replace cylinder head (11) if flatness does not meet specifications.
