What we used to refer to as "Feulie Heads", betrayed by the double camel humps. Light weight blocks and heads are always cool. Go for it

Mark: I'd want to find out from Speedway who makes the PN you are interested in... and what kind of warranty against 'cracking' etc.. There are some makers of small block aluminum heads that do not enjoy a great reputation...

Speedway machines the castings themselves I forgot to ask who cast them. I liked them over Trickflow because they are 64cc over 60 cc

Check the exh port location so you don't get in trouble with header fitment.

I haven't found the warranty clause. But, they're not the cheapest heads on that site and the priceless Edelbrocks are all sold out

No headeraches on this one has 2 inch dump rams horns, would like to go 2.5.

Speedway also sells 2.5" Rams Horn exhaust manifolds that are seemingly cast from the originals... (seemingly identical except for the PN cast in)... about $100 per pair...

I actually bought two sets from them when they had a sale a few years ago. Recently sold a set for more than I paid for both sets. I kept a pair for this project.

I would run these. Looks like a good choice for early 327.

Paint them chevy orange if you want to disguise their 'aluminium nature'... :)

After spending the money for them I hate to do that to them, thought I would toss this out for opinions. Intake is also aluminum 3x2.

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.

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.

The aluminum surfaces which I've seen 'oxidize' are generally 'cast surfaces', and possibly the somewhat porous nature probably causes the oxidation over time and with exposure to moisture and temperature changes. Prepping and painting those surfaces prevents the aluminum oxidation and promotes easier cleaning.

A 'machined' aluminum surface isn't as likely to oxidize, and is easier to keep clean or polished than a cast surface.

PS. I've used 'argent silver' urethane paint to paint aluminum parts which appears 'aluminum like' and is much easier to keep clean.

If 56 was a daily driver I would be more concerned about oxidation, as it stands its more of a garage queen.

You must live on a different planet. The only problem I have with as cast aluminum is when it gets fuel or oil on it, then gets heat cycled with dirt included. That's very hard to clean up. But it's not oxidized, it's just dirty.

My buddy who double checked the valve job and assembly of the heads told me they are cast in a better grade of aluminum than the China import crap.

Why is anyone still buying that crap? The money people save in the short run will be payed back out again, as soon as that junk fails its service.
They did a documentary here, a few years ago (they dare not repeat something like this again, nowadays) showing what happens when a cheapo drill gets put into severe service. It starts to smoke, melt and then quit. Then they tested a made in this country drill and it kept going, without any hint of wanting to give up.
The money you waste on that slip-shod stuff eventually goes to their building up their military

I have an assembled long block, need to pull 350 to get the 3x2 setup. Then I have to figure out what to do with it.

It is alive the February of 62 date coded 327 runs again this time with fast burn aluminum Trick Flow Camel Humps. The 3x2 setup still needs fine tuned and the 700r4 cable adjusted. I kind of miss my old th350. A few hiccup's in the install I was unable to fit the road draft tube with Turbo Adaptor Mounts and 700 dipstick. Had to use the nipple and pcv valve form a later 283/327.
