Polishing engine
My plan is to make my engines rocker cover go from looking like this:
To this:
From what i understand, i just need to take the paint off and then rubb it down with increasingly fine emery cloth. Is this right?
Also, can i remove the paint from the rocker cover using brake fluid (or similar) or will this damage the aluminium?
How long can i resist the temptation to drop a V8 in?

First off. it will be hard and dirty work.
You need to get the paint off (use paint stripper (read label!!!), then bead blast - fine glass, and I would then sand any casting flash off. Give the
whole thing a quick polish to see how rubbish the casting is, then sand smnooth, then polish.
You'll need a bench grinder with 3/4 hp as you'll be putting quite a load on it. Also need mops and soaps.
You may find it better to do the preparation work yourself then have it professionally polished.
I polished my stainless exhausts and while they look nice, it took a while. Yeah, not the ones in avatar

I have brake fluid in the garage
I would obviously use paint stripper if it were going to be better

You'll also have the slight issue of the covers not looking anything like each other, but if you can overcome that, getting it polished should
be now bother! 
Otherwise, expect many hours swearing at them for having one awkward to get at scratch.

Are you planning to grind off the shallow 'fins'? If not, will you leave the black coating inbetween them?

Seriously, its got to be worthwhile looking at buying an aftermarket one already polished. I quite like polishing ( ) and making stuff look clean,
but that cover is going to be a nightmare.
Id consider all options before going down the locost route. It might take a few months of saving, but chromed or polished ali aftermarket ones
already done would be so much better.
Kindest Regards,
Richard.

do not bead blast,
paint stripper
then single section sisal with a grey greaseless wax
finishing of with either a cool air mop and a white greaseless
or a swansdown again with a with greaseless
take ya time and you'll be well chuffed

Does it make your car go faster?
Each to their own 
Personally polishing engines is a bit like cleaning cars IMHO!!! IE a bit of a PITA and temporary at best....
I'd give it a quick wipe and spray it satin black for the "stealth" engine look....

Satin black works for me. Bonnet covers it anyway. Best to have some nice wheels than nice rocker cover.
Dont do what my mate did. had zetec cover shot blasted. Then crackle paint. Looks really nice. Got car running and oil found the hidden pocket of
sand....................
BTW - i dont ever think you can get the first pic looking like 2nd pic just by polishing alone.
