screenshot....hear that everyday, don't know what it is much less how it works. When I'm on this website, I use my home computer. Never been on that website from my phone.

Could have been done in a sink EDM. But a lot to go through for that. Unless they are some sort of forgotten early 'aftermarket' head.

A good artist that got creative...that's it. I had a guy etch a name on the side of a beer glass one time,,,completely freehand. It was so perfect I bet nobody would ever believe that wasn't done by a machine.

The fact that this deception was only done to one head of the pair tells you flat out how stupidly time consuming that must have been!

Or the car had air conditioning and no one would ever see the other side so they didn't bother.

Finally was able to upload using my phone…. Lots of third party help lol….

You can see an errant tool mark from the saw or cutting wheel. So definitely was carved by someone

I may be in the minority, but I think it is a really cool little trinket they created. I do not believe it was cast that way due to the difference in the finish on the little pads vs all the surrounding cast iron. It is much smoother where the art was "added". But I like it. Thanks for the close-up pictures.

Look folks, face the hard facts here please!

To add those two details with out them being made on a small Plack and screwed down like we see with the interchangeable casting numbers would have required a reverse impression of those being made to the main sand cast molds.

Changes like this to core molds cost a fortune and would have never been approved for a production run of heads, no less to cast up just one head!

[scott70]

I dont think really anybody here is thinking these were casts. Zooming in you can see the cut marks,,,probably took someone maybe a half hour to do it. Whoever did it thought maybe someday someone will see it,post it on a website for others to discuss if these were secret pontiac heads or not. Loll,,,,I guess it worked!

LOL.... Exactly! We did something similar once. We ground off the casting number and added a bow tie. I like the Indian Chief and Pontiac crest idea better.

Well the stock air cleaner heat riser shield / pickup housing does fully cover the center exh port section of one of the heads.
That being said you still can clearly see the rust pitting that the rest of the top of that exh port area has , yet those two added areas do not.

[Scott Stoneburg]

In my opinion, I do not think this is something done at the casting level, but it's cool that someone took the time and skill to do it. Probably took way more time than initially thought it would but I would not consider it "stupid" I have done several things to my car to personalize the modifications. Which many people would not spend the time to do, but that's ok. I say good job to whoever did this! Cool

Mikey likes it. Somebody had fun.

My guess is NC something, given the flats are smooth.

Maybe a miniature NC mill? EDM could do it but that equipment seems beyond the means of a hobbyist.

The head is not centered, so I'm thinking hobbyist and a learning curve.

[grandam1979]

I do mold repair work and use pencil grinders and right angles Every day. I think I could do the arrow head in a few hours and the first one is always the slowest. The Indian head would be a little harder I’m a mold repair guy not a artist but with a little practice and a drawing it could be done.

FWIW, just my opinion, and because I did work in a foundry for about 6 months about 55 years ago. It seems to me that these heads have a raised portion where the insignias are. I would surmise that some union worker, that was bored, used a penny to make the insignias on and glued to to the pattern before the casting was made. It may have been patterns that were scheduled to be retired, or reworked.

The reason I say that, is because a penny is made of copper, and very easy to work with hand tools because of the malleability of that particular metal. My money is on a pattern modification, rather than making the design on an already cast head. I however may be totally wrong, wouldn't be the first time.
It just seems to me from the pictures that the portion is raised above what a stock head would have material in that area.......

Just for grins, I'd try laying a penny over the insignia to see if my theory has any merit.

Thanks to the OP for making the board aware of this abnormality, that some frustrated artist has made.
