How long should stock push rods be?

If the piston is marked with .030 does that mean it is bored .030?

How can I tell if a cam is good or not? Worn or not?

Yes, those should be .030 oversized pistons. Is there a part number on them? It may be on the bottom. The cam lobes should be egged shape and the lifter bottoms flat. One of the BBO guys will to comment on pushrod length. Is it the stock non adjustable valve train?
