Here's what I'm starting with:



I have never removed anything from a motor from the top end or the bottom end, just accessories. Are there any tips for removing say, the pistons, main bolts, crank, or cam that I should know about? Like some way to prevent scarring, etc?

Also, are the heads relatively straight-forward, or is there something there that I should look for when tearing them down as well?

Thanks, I really don't want to mess this up.
