Why does my head not have screw holes on top to attach pushrod cover?

What Engine is this?

That is the head and not the block
There should be two screw holes about a foot from the center (fore and aft)
Chevrolet depended on gravity on the top.
Note washers under head bolts ???

To repeat Jon's question...
What engine is this?

If I remember right, early sixes like my 1929 have no bolts/screws along the top edge of the side cover.
A lip hanging down from the edge of the valve cover is all there is to hold the top of the side cover against the top edge of the head
There is a line of screws along the bottom edge, and acorn nuts on studs half way up the cover, but that's all.

So what year is the engine you are working on?

The motor is in a 33 master. Not sure of what number it is. The oiler on the head is correct for 1933 per picture. The push rod cover has holes along the top but not in the head.

I could be wrong,

But it looks like you may have a head from an earlier engine.
The washers under the head bolts suggest something funny is going on there as well.
And some of your rocker arm adjusting screws are screwed out near the limit of their travel.

What number is cast into the head?

I will check when I get home and let you know.

I will check when I get home and let you know. The motor was running prior to stipping down.

Picture of block, picture of head coming.

Why would someone put extra washers? Stretched bolts?

There should be a six digit number (like 836961) somewhere on the head.
We need to know that number.

This is outside my expertise.

So can someone else verify...
Is that a date code on the head showing August 6, 1929?
And conveyor number 13?

Found the number under the rocker arms. Looks like it is a 1929 head, therefore no holes on head for cover. The block does check out as 1933 number. Not knowing the history of the car is proving to be interesting. As I indicated the motor was running when torn down. Question would be do I keep the current head or swap it out for a 1932 head that I have on another motor that is not running? Opinions are welcome.

The 1932 head is an improvement over the 1929.

I second what Gene says.

The '29 head has smaller valves, and the intake and exhaust are the same size, which will limit your horsepower.
The '32 head will breath much better.

Those early 6 cylinder heads were famous for cracking. If you have a '29 head that is not cracked, I'm sure there is another Chat member who would be glad to purchase it from you. Be sure your '32 head is not cracked before you install it.
Maybe someone has a '33 head to trade.
