I just removed the head from my 31 and this is what it looks like. What can you tell be from the pictures.

Whoever has done this work it was on the cheap. The cylinders were bored and not honed. I can see the tool marks in number two cylinder. As Colin said it's burning way too rich/ pumping oil as well.
The cylinder head gasket wasn't sealing around number one cylinder.
Looks like it has some valve seats in it but the block wasn't cleaned properly.Water jackets full of crud.

If I were you and this were my engine I would drop the oil pan and inspect down below as if the skimped out up top it's going to look the same on babbitt and camshaft/crankshaft down below. I wouldn't be too far on a limb to say an engine rebuild is in your future.
 
Out of curiosity, any idea of how many miles on the engine?? Could this have been band aided back in the 40's, 50's, 60's, 70's or a rebuild in the past 20 years??

Just a guess but I think it was rebuild about 25 years ago and has about 3000 miles since then. It should have not been a band aid being part of a complete frame off restore that took 5 years to do but it does look like there was a lack of attention to detail and some corner cutting.
 
In restorations, many times when the money gets thin the running gear and motor are the parts that are cut in the corners and suffer. This is because they can be doctored up with quackery and the buyer or owner is none the wiser or just don't care. It's all about the looks, bling sells.
 
Here is a couple of pictures of a piston. What can be learned from these? They have a stamp mark on the inside that says sep 89, is this a date? Are they ok with new rings if the size is right?

They are probably Sealed Power or Silvolite or Nylen pistons.
Really doesn't tell much other than how old they are.

I'd have to see the outside of the piston and what the lower outer portion of the piston looks like for wear. Also what do the rod bearings look like? Crankshaft journal surfaces? Can you rock the piston on the rod as that will show if the wrist pin bushings are worn.

As I mentioned this morning the cylinder walls aren't healthy so I would still say while it's apart do it right and get it rebuilt by a reputable rebuilder.
That has the equipment to do all the work by today's standards not a backyard weekend warrior.

Agree. And many owners barely drive the car, maybe for an ice cream or to church and the rest of the time it sits in the garage as a pretty thing to look at. And even though poorly built, the engine handles such menial tasks OK. Then another owner comes along who expects more, wants to tour, etc, and all he** breaks loose with the motor but the rebuilder now is so far removed from the picture that he gets away with it again. Have seen this time and again.

Case in point: The PU in my avitar

Was "restored" in the late 80's. When I bought it 4 years ago (20+ years since "restoration"), it had 1,500 miles since "restoration".

The words "restore/restoration" are in quotes, because that is what I was told prior to my purchasing it. The body work was/is absolutely beautiful. Not so with the mechanical. I have had to replace most of the moving parts in the engine except the crank. The upper mains were OK, but the lower caps have all had to be re-done. Water pump and fan (which when the fan let go, another radiator was necessary. Transmission had to be replaced (probably could have been rebuilt), as did the steering box. Even the speedometer! And I could go on and on.

Perfect body, crap for mechanicals. I did get a good enough deal on it $$ wise that I'm not too bad off in the long run.
 
On another side, I was contacted today by a person wanting to know which way the splits on a set of split skirt pistons faced. No name was given and that is probably good for him. After a short conversation, he divulged he was "rebuilding" a motor to put in a car "to get rid of it". He claimed it had a bad leak at the rear main and smoked. He was only putting rings in and filing the caps but the worst thing he divulged was that it had a rope seal installed in it that he removed. He claimed he is going to install a cork seal in it to stop the leak. He also claimed the slinger was still on the crank so, the cork seal won't fit as intended. When he is done, I suspect it will leak as bad as ever but if it doesn't it won't for long. Too bad for the person who buys it and I told him so.
 
It's a shame there are so many *** holes that knowingly sell broken worn out junk while lying about it! That's why I like to get stuff from friends, because when I get something at a swapmeet, I get it home , and then see why it was for sale. Argh!

Some times the seller is completely unaware of what is inside the engine having paid big dollars for an engine job that is substandard. Recently I pulled my 1910 Hupmobile engine to bits after a $15,000 engine/gearbox rebuild 2,500 miles ago by the perfectionist previous owner. Found a 40 thou bend in the camshaft and main bearing bolts that had been tightened up so much they had stripped out and were little more than finger tight! The sliding gears in the box had been attached to a carrier at an angle resulting in all sorts of complications. All fixed now but I know the previous owner had no idea of what had gone on! -Karl
 
This is why I am waiting for Terry to finish the New Model A motors. I hear all these horror stories about rebuilt model A motors and just can't bring myself to have the motors that are in my cars rebuilt. :(
