If it's necessary, ya do it. It shouldn't be bad at all, just a quick spray and wipe. same with the valve cover side to ensure it's clean.

Do watch the wiring harness- if you see signs of it cracking like I said, stop, turn around and run away for another day.

PS on the plugs, if you do them,make sure you get non resistor plugs. They probably won't be found at the local auto parts store- if you ask the parts guy their book will tell you that Resistor plugs are OK.

Resistor plugs are NOT OK.
