You have the Edelbrock Performer RPM air gap manifold, which is very good! Look like Harland Sharp rockers to me also. They should be nice pieces for a street engine. Nice find. The '46 looks like it will be a real nice driver. And I tried the 650 double pumper on the street for a while. They make for a very responsive engine, but whew they love that gas! Enjoy the new project Don.
