I don't use nylocks "inside" the engine.

You don’t use nyloc inside the engine, that’s what the waves washers are for

Ok, looks like I can pick some up locally at a reasonable cost.
Things are already torqued, so I guess I just go around in order and remove, replace, retorque one by one.

I have plenty of non-Nylok nuts too.

The nuts I have on hand in quantity are:
1) Cadmium plated nyloks
2) Cadmium plated prevailing torque
3) Stainless steel

As noted, #1 is not good to use inside the engine. Are either of the other two options good? Or do I need to pick up a different type for these studs of the heads-to-cam towers?

Just use standard 8.8 8mm nuts with wavey washers.

I'm usually scared to use stainless hardware in/on an engine. If you ever lose or drop one in the engine, having it be magnetic can be an important advantage.
