318 rebuild/overhaul kit

I think this is the right forum section for this. I bought a 68 Dart last Christmas and recently found all the casting numbers on my engine. It's a 74 block with 67 heads and intake. It's pretty greasy/oily so I want to clean and rebuild it. What overhaul/rebuild kit should I go for? It starts and idles pretty good, haven't checked compression but it doesn't seem to have any excessive blow by, so I'm thinking just a good wash and full gasket set. That's where I need help. Do I need to piece together multi year gaskets or will a certain gasket kit cover the whole thing? Also, the 2bbl carb probably needs rebuilt, it always needs starter fluid for the first start up then after that it'll start on it's own. Thanks in advance.
