To replace the exhaust cam plug on my '95 Integra LS (non-VTEC) do I have to remove the whole cam shaft first?

The Haynes manual is not too specific on this particular repair. Here is what I think needs to be done:

1 Remove spark plug wires
2 Remove valve cover
3 unbolt cam holder
4 Remove cam plug
5 clean off area around plug and apply sealant
6 Replace cam plug
7 reverse steps 1-3

Did I miss anything?

Thanks

Sunny
