Replacement part need help thx

Have a 01 Lanos need to replace the head gasket/ seals. Where is the best place to get a set? I have found them on NAPA, but for twice as much as anywhere else. Found them in a few ebay stores for many different prices and on parts dinosaur for 90ish. Not sure which ones are OEM, OEM spec, or just cheap aftermarket. Please help if you've replaced your head gasket set. I'm located in Jax, FL. Thanks in advance for any information.
