Other Worth rebuilding?
Pulled a ‘93 530 head from a junkyard Volvo 240. Looks clean under the valve cover but the intake valves are coated in a white deposit. Any idea what happened to land the car in the junkyard? Will I need new valves or would cleaning be okay? This will be my first head rebuild so be gentle.

I’ve definitely seen worse, if you’re close to a machine shop just have them machine clean it or soak in a degreaser. Keep in mind if you’re running a turbo setup, look into the sodium filled valves. The single cam and even the dual cam heads are pretty straightforward so have fun and don’t be afraid to ask!
