1928 chevy 4cyl motor

If anyone has a set of 1-1 rockers they would sell them please give me a shout,

 

Can anyone tell me if there are any aluminum or pot metal parts present in a stock ‘28 Chevrolet head?



I’ve held onto this one for years just in case somebody gives me a ‘25 Superior some day. It was recently in a basement flood, so I want to tear it down, clean it up, maybe paint it, and put it on a shelf in my garage where I can admire it and it can’t get wet again.

Step One of this quasi-restoration is a thorough degreasing and I was contemplating using oven cleaner for the initial clean-up, followed by kerosene or diesel fuel. Before I start, I wanted to confirm that there’s nothing non-ferrous in there that the oven cleaner might eat.

Thanks!

 

There's nothing but Iron or Steel components in the two '28 Chevrolet heads I have here.

On a very rusty '28 head I restored ten or so years ago, I had to use a hydraulic press and heat to get the valves out of their guides.

Edit: Like this -

 

I think you're safe here, but there is oven cleaner that is aluminum-safe, should you have a need.

It is not quite as powerful as the regular stuff, but it is still a great help in removing aggressive crud.

 

Thanks, fellas! As a follow up: What color were these engines painted when stock?

 

I have not seen aluminum or pot metal in either of the '28 heads I have. After you get the grease and crud off soak it in a citric acid bath. That will remove the rust without hurting anything else. It may help in getting it apart more easily.There are threads here about using citric acid to remove rust.
