318 rebuild suggestions

Ok so first thing I will pull the heads. Are there good youtube videos on how to check for cc. I have never compression checked before.

For measuring the gap. I just turn the crank until the piston is at its highest point correct.

I am defiantly a little confused. What cam should I be looking for. Or don't know until a cc is done.

Thanks

Gotta learn somewhere...

I would wait on cam choice,until you figure out what you want to do ( cylinder head/and compression wise). Makes it easier,in the long run.
