I have just purchased a used olds 442 400 engine. I assume the specs of the pistons are .030 as the top of the piston has that engraved in it. How do I find out the stock length of push rods for. the 66 olds 400 engine?

How will I know if the main bearings and rod bearings have up sized to a 010 020. 030 etc....

How can I tell if the cam is still good to use!

The reason I ask all these questions is that when I pulled the head all the valves and spring and seat etc. had been redone. The valves had never even seen fire and still had marker numbers on each valve.
