My First 318 Rebuild

Update: on Saturday I picked up a .020 over 318 block with a TON of parts for it. None of it assembled, but it has new cam bearings and came with basically everything you need to build an engine. Came with kb167 pistons, as well as stock replacement pistons, both .020 over. Aluminum intake manifold, mystery small block headers, b body oil pan, freeze plugs. Everything except heads, including rocker assemblies.
Now I need to pull cylinder heads off the old motor, cc the combustion chambers and start blueprinting this engine. Once I know where my CR is going to land, I'll call Oregon cam grinders and figure out what I'm doing with the cam. I'm not throwing away the idea of doing a roller conversion, mostly because I want the peace of mind, and also that those kb pistons probably deserve a healthy cam.
