Head gasket time, modification recommendations?

So, I’m changing my timing belt, pullies and water pump because the timing slipped a little bit. Didn’t slip much, but the belt is pretty shredded.
I pulled the head to make sure the valves didn’t all get punched by the pistons. They’re fine.
Since I’ve got the head off, I’m thinking about gasket matching the head to the intake and exhaust and thought to ask if anybody has any modification recommendations, in general, since I’ve got the top half of the motor removed now, anyway.
What have you done?
