Thanks, I will take the liberty of painting it gloss like the frame and front suspension then.

Here is the Trico assembly I used for my low windshield SP310:-




Sorry, that isn't what you asked!

I’m fully embracing the “while I'm in there” chaos that happens when I tear a motor apart, and I’m wondering if I should strip the chrome from the valve cover or embrace it and try my best to clean it up... thoughts?

Since the valve cover is one of the outermost parts of your whole car, I suggest that you skip it for now and get on with the higher priority things first.

Yes, agreed with above... don't be the guy that says "Its better to look good than to feel good...". Nothing makes a Roadster look better than a shift from second to third at 6500rpms...

Back to the grease, Simon..lol
Linda

The cylinder head is about to come off and get shipped to a machine shop... dont worry, Im getting quite greasy.

Make sure that you number the rockers so they go back on the exact same lobe on the cam!!!!!!

Simon, are you sure it's chrome? Unusually if someone changes the appearance of the valve cover its either polished or painted. I have never heard of someone chrome plating one. A highly polished peice of aluminum will look just like chrome. If it is indeed chrome than the dirt and discoloration should wipe off without much effort. If you get some aluminum polish and try it on the bad areas and they come back to life than its most likely just polished. If you determine that it is polished than you can either repolish or try getting it bead blasted. Don't use sand, as that will leave a rough finish. even the bead blasting will leave it a duller than stock appearance and it will probably get dirty pretty quick. The easiest way would be to either bead blast it ( or hand sand it) and then paint it. If you have access to a large ceramic tumbler that would probably be able to achieve the closest stock appearance. The problem with polishing aluminum, especially when it resides in harsh and dirty conditions, is that it will have to receive regular maintenance. If you blast, or hand sand, be absolutely certain that no debris gets on the inside of your valve cover. And, as others mentioned, concentrate on the important things first! The asthetics can be addressed later. Good luck moving forward.

Im pretty sure its chrome... it wouldve been done in the 70s/80s prior to the car being parked in '87

Rub some polish on it with a cloth (any polish really) if it turns black after a while it’s polished if it only cleans without turning black it’s coated
