Paint them chevy orange if you want to disguise their 'aluminium nature'...
Natural aluminum oxidizes, and isn't very pretty. Paint them with something (chevy orange, aluminum?, or Clear coat, OR any other color you want to display your engine)... with aluminum heads and intake, your engine is lighter by ~ 100 lbs or so. with those aluminum castings (cast like cast iron stock heads), painting them as you would cast iron heads disguises the fact they are aluminum. With aluminum heads, you can get by with a little higher compression and less tendency to knock with low octane fuel.
It all depends on what you want to do with your engine. Paint the block aluminum too, and tell everyone it's ALL ALuminium..
I'd polish them up as shiny as possible
I'd paint 'em the same color as the block
Have you ever had a set of aluminum heads? The ones I've had stay the way they were new, dirt and grime is their main enemy. But that's true of anything.Natural aluminum oxidizes, and isn't very pretty.
Yes, Rick. and three ALL ALUMINUM V8 cars.. still have two of them plus another one... and all of them were and ARE painted... How long have you had your aluminum heads Rick? and they aren't oxidized? so shiny like new eh?
We haven't seen any posts from you lately Rick.... so what are you working on your Trifive most recently?
First pair from Brodix almost 25 years ago. They still look very nice. Since then heads from Dart and Chevy. They still look nice too.
As far as my posting, I got tired of Harry and Al_Dente so no replies to them. And I don't have to polish or paint my aluminum heads, so no posts about that.
Now that you mention it Rick my aluminum BBC heads on my Camaro drag car still look good after 10 or so years. I think I will not paint them could tell people the were some of those ultre rare early 60s Grand Sport Vette heads.
