Doing an aftermarket head upgrade on my 360, will have the stock iron 360 heads available to sell, but have not been able to find many resources to value them. They're in good working order but will obviously need to be gone through.
 
Depends on condition, valve sizes, part quality, port work, etc.
Bone stock, so whatever the valve sizes were that came with, no port work at all, it's an original mopar head, not reproduction. Condition wise, it runs well now.
 
What casting numbers?
Hard to read them to be honest. Included pictures

teen police heads....
4323345 318 Police 1983-86 1.78 1.50

4323345 – 1983-1986, 318 LA-series small-block, 1.78/1.50 valves, Police, roller, 69cc – 77cc

cant quote value but they appear to possibly be 318-4bbl heads that are not that common as the 318 had a very limited life as a 4bbl motor.

4323475 – 1985-1987 318 LA-series small-block, 1.88/1.60 valves, 69cc -77cc, 4bbl
 
I’m the first to say “never say never”, but I seriously doubt you’re going to pull those heads and find they have 1.78/1.50 valves in them.
 
I would look under the head where the exhaust heat crossover is for the casting number. You said you have a 360. IF those actually are 318 heads, then they didn’t come stock on that engine.

I'll check it when they come off and update the post. Aren't the blocks pretty much the same for a 318, 340 and 360? I thought the CI difference was internal and you could do some different head/block combinations. They're stamped as 360 and the engine ID was a 1970 360 from the Windsor plant, so I'm not sure what to think at this point.
 
Any how - if you are looking for a price to sell as is? Honestly with out particulars on the heads and guessing on Age, wear and desire-ability- swap meet price is $50 per head for cores. Unless you can prove they are better than cores that’s all you can get reasonably. Some needing that exact head may pay more. Aluminum heads of better everything have flooded the market making cast iron heads very old skool and not as desirable.

Sorry, your post is a little confusing to me.
I’ll attempt a stab at it.

Yes. The big differences are;
The 340/360 have a slightly different drivers motor Mount boss on the block
The 360 has a bigger main journal crank and takes its own oil pan
The 360 & 1 year only (though it has been reported in showing up a year earlier at times) ‘72 - 330 are externally balanced and do not share the same balance between them.
The bore and stroke do indeed make up the displacement. Each block is limited to the bore size because the cylinder sleeves are limited in there thickness. Stroke is limited to what is available.
Con rods may interfere with the bottom of the cylinders. Notching will be required with some con rods.

and you could do some different head/block combinations.
Yes! Though sometimes that may be a step backwards.

There stamped? As in the head? I see a cast in 360 on the intake runner. This has nothing to do with what the head came on. Zero!
Just look where I said and you said your going to do later. The last 3 digits of the casting number is all I need.

The engine I.D.’d as a ‘70? This is good!
If you bring it to a machinist, have him sonic check it and write it all down. This is really good to know. Try and NOT to bore it larger since thicker is stronger!

Below is the report to a block (or 2) I had checked for wall thickness.

You lost me here LOLOL
Did you mean 318 vs 330?
 
the numbers on those heads cant be from 1970 so they have been replaced. teen heads on a 360 would make gobs of torque but would be all in at 4000 rpm. RV style. Not common but not unheard of. The 360 callout is misleading measure the valves or just measure the height of the intake port. the 318 is shorter rhan the 360 port and should be visible without pulling the head
1.05x2.07 is what a 318 intake gasket is stamped to. 1.16x2.28 is 340/360 intake port size.....post your results!

Sorry, I wasn't clear about things, by stock I meant, unmolested or unmodified, not necessarily that they were originals. This car started life as a slanty and a previous owner made the change to the current 360 and the current heads. When I mentioned stamping, I meant casting on the top of the head/runner, my apologies for the inaccurate language. Someone else is doing this rebuild and I've asked for some pictures of the underneath of the heads when they're removed, hopefully by tomorrow I'll have a few more images.

As for the condition, this car ran well with these heads, so I don't think there's anything wrong with them at all, I'm just going with a top end rebuild to a newer cam, lifters and heads.
 
'308' heads off a 360 van or truck are very good newer 360 LA heads, great exhaust port. Going AL? Speedmaster?

Still looking at head choices but Edelbrock Performer RPM, and Speedmaster are both at the top of the list so far. This car will never see a turbo or supercharger so I don't need to go insane with this, but new aluminum heads will flow better than these, even with a good port grind and valve job. Having a warranty is a nice plus also.

What's the rest of your combo? Stock 360 I saw so far. A set of aluminums may help a bit with a little more compression and better flow. What cam, intake, carb, and exhaust are you running. Stock compression may be around 8-1. Just sayin'

Replacing the cam, lifters and heads while keeping the intake (Weiand Action Plus), Holly 600 carb and hedman headers. Looking for a little more grunt and a touch more HP at the top.

Haven't decided yet on any of the replacement parts, working with a local guy who's pretty good with setting up motors. He's a fan of Lunati cams and I've been looking at Edelbrock and Speedmaster for heads.
 
Update for everyone, and thanks everyone for the knowledge. So, the casting numbers are 345, designated as a police 318 head, which to me is totally bizarre that police cars were running around with slightly built up 318s instead of big blocks. Regardless, they both have cracks in them big enough that the machine shop suggested replacing them, so I'm now in the market for new heads and these are worthless as paperweights.
