Sorry to bother. I have seen the answer before, but can't find it here or in my noggin.
I am ordering new head bolts-low head.
Do I need head bolt washers?
Thank you, Paul in Tacoma

No washers needed unless you're installing an aluminum head.

Won't hurt to double check since it's easy to do. After making sure the holes are cleaned out and the threads chased with a bottom tap, set the head in place without a gasket and run the bolts in. If they snug down to the head you'll know they will be okay once the gasket is in place.

If you decide to blow the debris out of the block holes with compressed air, have a vacuum cleaner sucking next to the hole, and be sure to wear eye protection! :-)

What Mark said, and cover everything else so you don't get crud in the cylinders.

Now now, blowing out compressed crud doesn't unlodge years of stuff lodged in the bolt holes, you need to clean them out by scraping until they are clear to the very bottom.

If there are bolts in the holes how does crud get in there in the first place?

David - back in the 20's both the bad gas of the day and the oil caused more soot in the combustion chambers than what we get today. When it got too thick, you would get symptoms like engine run-on and spiking and had to pull the head and scrape off the carbon. Some of that scraped off carbon has a tendency to fall into the head bolt holes, so there was even an accessory invented and sold for the purpose of plugging the holes while working on the engine - short headless screws with a screw driver slot:
