I have a stock 77 with the 350CID L48. I want to get another set of valve covers maybe Chrome and i see were its list 2 types Short or Tall. What type are on my 77? Picture below is what's on there now.

I'm thinking stock (yours) is short and tall is for higher lift or larger rockers.

Why not just get yours chromed?

I think it's cheaper to just get a set already chromed from Topflight. 

C3 1968-1982 Chevrolet Corvette Small Block Chrome Valve Covers - Short - Black Chevrolet & Red Bowtie Inlaid - Auto Accessories Of America (topflightautomotive.com)

All small blocks were delivered with the short valve  covers. Tall covers are only needed when using roller rocker arms.

Thank you both!

And they look like cheap, aftermarket valve covers.  I'm not a stickler for originality, but the Corvette valve covers are better looking.

Those finned valve covers you have would polish up nicely, and look almost chromed. I like those valve covers, polished or as cast...I think they look nice on a small block in any car, but...that's just me. 😁

Hello, I totally agree with Mr Apple. A little grease on the elbow, and some #4 steel wool, you'll be proud to lift the hood at any venue!

Me three.  Polish them up.

Thank you all for the advice, I'll try and polish them up.

I'm a rubbing! Rub Rub Rub! 

Haven't rubbed this much since i was a teenager! lol

Any cleaner that might help? 

Hand polishing those things will be a chore! A buffing wheel on a grinder would make quick work of them, but of course not everyone has a bench grinder that could be used for polishing, so...

I would suggest a metal polish such as Flitz, or Mother's Aluminum polish. Either will require a lot of elbow grease, and will turn your fingers black. A quick rub-down with some Scotchbrite pads before buffing will also help clean, and smooth the surface for buffing. 

Here's some of my last polishing job...'81 Goldwing 1100 engine stuff. Set up one of my grinders on my rear deck railing, and mounted a buffing wheel to one side. I bought some buffing compounds to use for this since it would work better for my set-up. Did pretty much all of the exposed aluminum stuff, and it all took me several weekend days to get it done. Even using a buffing wheel, my hands got nasty! I would highly recommend using latex/rubber gloves! 😁

Well, this is ther best I could do!

I'd say overall they came out nice. For the spaces in between the fins, you could paint that area, and make them stand out even more. It's really hard to get down in the to polish, so putting some color in there makes the polishing effort on the areas you can get to worth it.

I have to agree with Mr. Apple, those look darn good!  Had those valve covers on "The Toy" and always liked the look of them.  Putting a dressing coat of some sort on the exhaust manifolds will add to the appearance.  Nice job!

"The Toys"...!!!  Save the Wave!

Where I've been in a Corvette...!!!

Thank you..This is all new to me..What type of dressing coat do you recommend for the exhaust manifold?

I used Calyx Exhaust Manifold Dressing on my factory manifolds. I thought it worked really good. Kinda messy but so far it has lasted several months. Sorry, not sure where I picked it up.
