Did you mark the lifters when you took it apart?
Where did you get the engine from most shops keep records of engines they sell. Even if it was a few years back they can probably tell you what kind of cam is in it.
At this point if its out i would probably replace the cam and go on. A bath room scale and a press can tell you abput the springs. Calipers will also be needed. But you should be able to find something that matches up minus a few pounds for age.
