Bead blasting is the only way those parts will come up really clean. Once you've got the corrosion off, you can set about the covers with some 600 grit wet and dry and a small block. After that they should be smooth enough to polish with Solvol and a cloth, again and again and again, it will take some hours to get a really good shine. Be worth it in the end though...
Those look like I970's Ansen covers by the way, no longer made.
Offer to "do the washing up" whilst the missus "puts her feet up". Slip the covers in the dish washer, along with 1/2 bag of sand, the contents four large bottles of T-Cut and some coarse wire pads. Set for 1 hour and 10 minutes, or the time it takes for her to read Heat or Hello magazine with biscuits and a cup o' tea.
Hey presto! Two sparkly valve covers and not an ounce of elbow grease required!

I agree - glass bead is the best way. Then polish from there if you want to. Intake will be fine as blasted.
Just be very careful about blasting any surface that will see the inside of the engine, I know people who ended up with a glassy sludge in their sump (so guess what it did to the rest of the engine ) after blasting the inside of valve covers.
From the stuff I have blasted, I would think that a good wire brushing after blasting would remove any embedded blast media....but still not sure if I'd risk it. Mask up properly though and you'd be fine.

that could come out more costly in the end thou, but worth a try
ticking away the moments that make up a dull day, you fritter and waste the hours in an offhand way.
Phil, that made me laugh so much that I couldn't help but Sal notice. I read her your reply and she's wetting herself on the other sofa, whilst threatening to divorce me
Blue, that's brilliant info. Might have to get some stickers knocked up like Dave suggests. How about it, Jeff?
Rockers and Intake on their way to Jon B for blasting next week, then just elbow grease from there. Pics to follow.
Thank's for all the help and advice

24 hours in a day, 24 beers in a case. Coincidence? I think not…
