L6 cylinder head data for a new report

Lacquer thinner or a rag works well.

Got most of the paint off. I see F0816CO. Vin matches the car.

It’s CQ 250ci/155HP L22 - thanks!

I am not sure that head was used on 250 cubic inch engines. It may be original.

It has a smaller combustion chamber and hotrodders would swap heads out to gain compression. Do you know for sure if the head is original?

Funny that you are questioning the head. When we got the car, the valve cover was black and the oil cap was the older style upside down cup type, not the flatter style. Sorry, I don't know the proper names. I've never seen a Camaro 250 with a black valve cover, so we repainted it orange. That's all I know about it.

You can scrub that area with a scotch brite pad and it should show better.

It was mentioned That the head my not be original. Can you please elaborate or tell me where I can find the information. Just a sidebar, it doesn't have a mono leaf suspension. It has a muti leaf. Why would someone change it on a six cylinder?  Just wondering.

Find what information?  We are researching the use of heads, trying to learn. If you can take the valve cover off, you might find a casting date. It SEEMS that the head you have was used on 194 cubic inch engines. So far we can not find use on a 250, but it is POSSIBLE. That is why we are asking. If we can find it being used on others, then we will know.

As stated above

Hey. I'm just learning too.

I also put a post on the Team Camaro site, hoping to get more data points.

This was reported from an eBay seller on a 250 cubic inch car that seems fairly original.

[bcmiller]

I looked in my 1968 Chiltons Flat Rate and Parts Manual. It has 2 part numbers but does not have casting numbers.

Hey. I'm just learning too.

See above. The same head that you have appears to have been used on a 1967 Camaro with a 250 cubic inch car currently for sale.

I found a post stating the 250 weighed more than the 230. Curious about this one.

That is not directly on topic, but at least for 1969 that seems to be true based on GM numbers.  A 250 cubic inch car is supposed to be 17 pounds heavier than a 230.  I have also been working on another report that compares height, weight and other dimensions for each year - along with some other factoids that may be of interest to a few.
