Quick update: this week I was able to get normal oil pressure to register after removing the Rothsport check valve, so it certainly seems like that was the root problem. My buddy and I actually got the engine started yesterday, but quickly noticed that the fuel return line was leaking...which means I get to drop the engine again today. Engine sounded good though for the brief time it was running. Thanks again to all for your help..
