There are a couple of different brand one piece gaskets that I have used on both big and small Chevy engines. I did some searching for black ones for some of the show engines I have built, so they wouldn't have the bright blue showing in a red engine or something. They have been pretty good to me, most have bushings so you can't over tighten them, and they won't split like cork. To some degree they are reusable. I use just a dab of silicon in the corners, but they look to me like they would probably work with no sealer. The only other thing I have noticed is that you have to be careful that they don't squeeze out between the timing cover and pan.
I need to drop the pan on my Vega wagon and put one in, I didn't have one when I assembled that engine, and it has an annoying little leak in the back corner.
