Those exhaust valves gotta go. They are already on the ragged edge of being warped and burnt. Pop all your valves and look at where they contact the seat- you should have a nice smooth consistent band around the seat and valve where they meet. If not, you might need some grinding done. If you are lucky you'll just need a bit of compound to bed in your new valves. Its not a high revving, high compression engine so you dont need to go overboard, just get them to seal tight enough to hold a teaspoon of ATF without it draining past them.
The other rust spots are all in the combustion chambers, above the valve seats and away from the sealing areas that make contact with the head gasket. They cant cause any problems besides maybe lowering your compression ratio .0000000001% and giving carbon deposits a handy place to hold onto.

In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
