Re: Cam Question
If you don't really care about the specifics of the cam you can extend the stem of a 2" travel dial indicator into the sparkplug hole and against the exhaust valve. If the valve travel is much more than around .300 the cam is probably not stock. Or, it must have hy-lift rocker arms.
If the specific timing/duration and lift numbers are important it will be necessary to get more aggresive with the tooling and disassembly.
