LT-1 Finned Aluminum Valve Covers

I just purchased a good used set of LT-1 finned aluminum valve covers. They are in pretty decent shape. What is the finish supposed to be on these things and does anybody know the best way to get it and keep it that way?
Thanks

Bare alum. You might polish them, then clear coat. Or to keep the flat luster look, clear anodize them.

Re: LT-1 Finned Aluminum Valve Covers

I have seen them painted silver but they should be polished. Best way is to polish them like said above. Use some corn startch on a rag when removing the aluminum polish (makes a big difference in the outcome)

They were a dull/satin finish from the factory.

I always thought that only the 69 had the dull satin finish, and that the 70's had the shiny finish. Maybe I'm thinking the part about the drippers.

Re: LT-1 Finned Aluminum Valve Covers

Those are great pictures. I always thought they were supposed to be kind of dull. Most of the covers I see are shiny. To me this isn't right. I wonder if a light sand blasting would give them a good look. What do you think?

They are supposed to be dull, the finish is the same for 69-72? I have a 6,000 mile 70 LT1 engine and they are dull like my 69.
I have restored covers for customers before by lightly glass beading them and then using 000 steel wool to lightly go over the covers using some varsol or solvent, to make the glass beading finish go away. It works OK and looks close to original IMO.
If you want them perfect send them to Jerry MacNeish.

Re: LT-1 Finned Aluminum Valve Covers

After seeing this Dave, i am going with a set of these, the air gap and Holley carb. I will need to get adaptors for my vortecs but I was going to need those anyway. So you got a set of these? Don't have to be perfect just nice and have that dull look. Might have to get the intake to have the same look.

My Edelbrock carb was stolen from the car port so Holley here I come.

Re: LT-1 Finned Aluminum Valve Covers

Sorry to hear your carb got stolen Joe

I think Chris still has the set of finned VCs that were on "Bertha". They were new GMs about 10 years ago. I polished them to look dang near chrome a few years ago, but I can make them look like Mark's in the above pic.

Re: LT-1 Finned Aluminum Valve Covers

I noticed in the pictures the pulleys are a high gloss black. Is this correct for a 70 LT-1? Would this also be correct for the fan blade?
Thanks

Re: LT-1 Finned Aluminum Valve Covers

It looks shinier there in that pic than it really is. About 60-70% gloss. Still probably a little more than factory, but I like a little contrast with the other different shades of black under the hood.

Re: LT-1 Finned Aluminum Valve Covers

RamAirDave,
Your engine looks great! What did you do to clean up your intake manifold and do you have anything on it to protect it?
Thanks

Re: LT-1 Finned Aluminum Valve Covers

Any one got a line on set of these PM me. Don't need to be pretty since the plan is for Dave to make them look like the ones above or a little more brushed/dull look.

Thanks
Joe
