Re: Cast iron or aluminum heads what do have?

I'm going to say cast iron because of the rust on them.

Re: Cast iron or aluminum heads what do have?

Pull off the valve covers and get the cylinder head casting number. Well, only pulling one of is necessary. That will give you a lot more useful information than just the material type.

Although, they have to be iron. Aluminum does not rust like iron will. Aluminum is not a ferric material, so it will only oxidize. Basically get very dull.

Here's some SBC head casting numbers.

Hope I helped you out.

Re: Cast iron or aluminum heads what do have?

Thanks for the help guys. Not going to pull valve covers off today but will keep that in mind for when I do if ever. Just trying to get the right spark plug and felt like having another opinion.
