What are these two plugs?

Welp, I blew the original 170 slant six in it in early February. I finally found a new 225 that at least turns over last week, and my goal was to drive it to my last day of high school. But sixes are hard to find where I am, and this one needs a lot of work, so I do not think I'll be done in time. Maybe I'll hemi swap it in a few years.
It's good to see a younger guy in the hobby and working on these cars. Depending on what the new engine needs, parts availability, and your budget it is doable to get it running in a month. Lots of slant guys around here with a wealth of info.
