I have some time before my cam arrives. Should I clean the top of these pistons? If so, what should I use? Thanks

You can clean that with brake cleaner and some petrol. Will be almost like new

Just bring your pistons to TDC on number 1, you'll be able to do #6 as well, rotote clockwise to 90*, clean other 2 at TDC, 90* more and so on.
Once you have done 360*, you are back at TDC 1 and all your pistons are clean.
Do not use any blade or sharp object as they will scrape the piston. Just be patient and lots of elbow grease.
Just make sure you change your oil before you fire it up.

Which B-12? There's a ton of them. Just the parts cleaner? I'd think you can use the air intake cleaner or the carb/choke cleaner as well. Both are aerosols. They are available everywhere.

nah let the carbon build up, maybe it'll increase your compression ratio and give you an extra 5 hp. lol.
They don't look so bad. but if you're are one of those guys that will always wonder if he should have then go for it.

Just finished h/c/intake today. Used scotchbrite and isopropal alcohol with the "PredatorZ" TDC method. Use clean lint free rags to clean up and stuff into those lifter holes.

I cleaned mine while everything was apart. You might as well while it's open and you'll sleep better at night knowing your domes are spotless!
Doc, Looks good my friend! I always used masking tape to tape over the lifter area to ensure nothing drops into the engine. Coat the bores with a slight coat of oil allows the crap to stick to the cylinder walls when the piston is on the downstroke and you can get it all out.

If you bring the piston you are working on up to the top and only use a scotch brite and alcohol and are concious about what you are doing- stay away from jaming things out to the edges, I don't see how you can go wrong. As with any of this, if you are pulling the heads off your car and have no patience, no extra time, then you are headed for disaster at some point.
