L6 cylinder head casting numbers
« on: July 02, 2023, 08:09:53 PM »
I am working on a report for 67-69 Camaro cylinder head usage. I have the SBC and BBC numbers pretty much done, but I am struggling a bit with the L6 heads.

I assume that the 230 and 250 engines used the same head and probably the same casting number all 3 years, but can any of you verify?

Include
1. The head casting number
2. The casting date
3. Year of the engine.

Thanks in advance. If you photos are used, you will be giving credit.

I love you but Im not taking the valve cover off. The ac compressor makes it difficult to see.these are from the passenger side because the manifolds are obviously on the other side.

I plan on using your picture that shows the 4886 external partial casting number.

Thanks!
